Ok, so you guys with functioning internet connections beat me to the press releases...lol

 

So some first hand pics, and a quick demo video of the aha service is being uploaded as I type this.

 

Some interesting info:

• The Z130 has a new built in ClearChannel Traffic receiver, a free service (forever).
  
• The X930 has the traffic tuner as an option, also a free service.
  
• The traffic receivers are NOT backwards compatible with older units (Z120 included).
  
• The Z110/Z120 will however get a software upgrade to add the aha service.
  

Over on their Facebook site, they imply the X920BT will ALSO get the update...can you ask them to verify that for the X920 users?

More info:

Aha RadioPioneer’s 2011 line of in-dash navigation models are the first to conveniently connect drivers to the world around them with on-demand, interactive, personalized radio. Via an iPhone™ with the free Aha Radio® Mobile App connected to the new AVIC systems, users can listen to the latest traffic conditions on their current road or commute road, listen to Facebook and Twitter updates, access hundreds of podcasts and other services such as the “Hungry†and “Coffee†stations which deliver real-time vicinity search results and directions to preferred restaurant categories listed on Yelp. Aha Radio offers over 100 content and podcast stations that can be conveniently accessed and controlled directly on the display of the Pioneer system.

 

App ModePioneer’s App Mode feature, which can be accessed only when the vehicle is in park and the hand brake is fully engaged, lets users view a connected iPhone’s video content from Safari, YouTube and other select apps* directly on the larger 6.1-inch or 7-inch high resolution screen.

 

PandoraPioneer was the first aftermarket manufacturer to offer fully integrated in-dash touchscreen control of Pandora internet radio streamed through a connected iPhone. Pandora access is available in both new-for-2011 navigation systems and has also been extended into the 2011 Audio/Video Receiver and CD Player categories. All Pandora enabled units display the currently playing album, artist and song information, while Navigation and Audio/Video Receivers also add album art display. The Pandora interface features full control of station selection, track info, and thumbs-up and thumbs-down feedback options.

 

AudioIn addition to Advanced Sound Retriever (ASR) that enhances audio playback of compressed audio files and an 8-band graphic equalizer, new features like Auto EQ Measurement and the Sonic Center Control which enable users to precisely calibrate the sound field in the car, have been added to both new navigation units.

 

 

AVIC-Z130BT

 

In addition to a comprehensive map database from Tele Atlas®, the new double-DIN AVIC-Z130BT features 4GB of flash memory, a 7-inch WVGA touch screen display, a 3D graphics accelerator, DVD playback, Dual Zone capability for rear seat playback, built-in Bluetooth 1 for hands-free calling and music streaming, USB connectivity 2 for iPod/iPhone connectivity, SD card slot, back-up camera input, built-in HD Radio and is SIRIUS XM 3 satellite ready.

Additionally, the unit features enhanced voice recognition, including the ability to input destination addresses by voice.

 

The AVIC-Z130BT offers Clear Channel’s Total Traffic Network 5 service for free via a Radio Data Service-Traffic Message Channel (RDS-TMC) tuner. With the included RDS-TMC tuner, ND-TMC10, the traffic service provides an overlay of real-time traffic events and conditions on the navigation map.

 

 

AVIC-X930BT

 

The new double-DIN AVIC-X930BT features 4GB of flash memory, a 6.1-inch WVGA touch screen display, a 3D graphics accelerator, DVD playback, built-in Bluetooth 1 for hands-free calling and music streaming, USB connectivity 2 for iPod/iPhone connectivity, micro SD card slot, back-up camera input and is SIRIUS XM 3 satellite and HD Radio 4 ready.

 

New to the X-series navigation systems is the optional RDS-TMC traffic tuner, Dual Zone capabilities for rear seat playback and a detachable hard-button faceplate for security.

 

The AVIC-X930BT will be available in March, and the AVIC-Z130BT will be available in April for suggested prices of $800 and $1,200, respectively.

UPDATE: Some dude on the Pioneer Facebook site got them to say this...

"...Yes, Aha Radio will be available on the 2010 AVIC-X920BT, the AVIC-Z120BT and 2009 AVIC-Z110BT via an additional map and software upgrade coming when the new 2011 models ship later this year. We'll keep you posted...."

Didn't miss anything lol. The Venetian network was brought down and then when everyone went to 3G, it crashed as well. Give me like a half hour to get to a working connection and I'll upload the pics and info from the press conference.

Whew...you scared us there, dude!

AVIC411 will be arriving in Las Vegas around 9:30am pacific, just in time to catch Pioneer's press conference at 11am.

 

Stay tuned!

Er, Jason...did you MISS the entire Pioneer presentation while waiting on a taxi line?!?!

Duuuuuuuudee....

Very impressive. I'm across the border in Canada and I wonder if this will be compatabile with us Canadians. I've searched iTunes and it looks like its only available in the US right now.

 

I wonder what else Pioneer has in store. I'm waiting to pull the plug on this unit for March. When can we expect more information? Today? Tomorrow with your hands on @ Pioneer's booth?

 

Anyways I'd like to thank you guys personally for going out of your way and using your own money to do this for the AVIC community.

No, the new units will be programmed to prevent Canadians from even TOUCHING THE BUTTONS...force field or something...dunno the details. lol

Okay...

Bets on how long before someone ports the new OS to the X920BT and Z120BT?

Would be great...and would allow existing customers to keep live data and traffic past the termination of MSN Direct in Jan 2011....

**UPDATE!!! BREAK BREAK! **

Some dude on the Pioneer Facebook site got them to say this...

"...Yes, Aha Radio will be available on the 2010 AVIC-X920BT, the AVIC-Z120BT and 2009 AVIC-Z110BT via an additional map and software upgrade coming when the new 2011 models ship later this year. We'll keep you posted...."

Victory for existing customers???

I heard a z130 and x930.dunno what they can do

Before I heard about the new integrated traffic tuner in the new Z and the eventual firmware update adding Aha-based traffic to the Z120 and the X920, I suggested one or more of the following:

1. A version of the XM tuner that brings BACK XM NavTraffic capability like the original one had?

2. An HD radio traffic-capable tuner (there is HD traffic now)?

3. Adding an FM traffic data service (TDS) to the base units with a software upgrade??

Sounds like they went with an integrated tuner to do #3 on the new Z130. The new Z130 also appears to have an integrated HD tuner...not sure if it will be able to serve as backup source of traffic data using HD's version of traffic.

At first glance, the new X930 does NOT appear to have the integrated traffic tuner, but WILL be able to use this "Aha" live data service to get traffic.

Also, the current Z120 and X920 will supposedly ALSO get the Aha live data capability with a software update.

There had BETTER be a replacement accessory for the MSN Direct tuner/service...and a new traffic solution for the EXISTING X- and Z-Series units...

By the way, if you guys gamble and win out there, EVERY user of AVIC411 expects a cut of the winnings...seriously.

This is a great topic, so I'm glad you started this thread.

 

Let me start out by saying that I love my 920BT, and am so excited about the many cool features of the unit. So I just encourage the engineers to finish what they started and make it a fantastic unit.

 

1. The voice recognition system needs to be scrapped and replaced.

No, I'm not exaggerating; I'm totally serious. When I speak voice searches to my iPhone Google App, it can understand 95% of what I say. When I try to use my 920BT to dial from my list of imported contacts, it can't understand even one. I have a standard American accent, and friends have also tried it. I've tried last name first, first name first, exaggerated enunciation, everything. It is just weak technology.

 

2. Recognize a spoken address.

I should be able to speak "Find 123 Main Street, Folsom, California" and be routed right to it.

 

3. Recognize a spoken contact's address.

I should be able to speak "Find John Smith: home (or work)" and be routed right to it.

 

4. Recognize a spoken business name.

 

"Find the nearest Burger King".

 

5. Navigation should default to current city and state

 

I should be able to start with my current city and state when typing in navigation parameters, and change them if that's not what I want

 

6. Navigation should list the street associated with the city I selected

 

If I've already selected the city, I shouldn't have to wade through street names from other cities.

 

7. You should include a printed (paper) user manual.

 

It's an expensive unit, so please give me a manual that fits into my glove compartment that I can reference whenever I want. There are lots of things to figure out for this unit, and if you have to take your laptop down to your car every time you have a question, it's hard to figure it all out.

 

8. Pandora should fully restore itself after a phone call

When I hang up from a call, my Pandora resumes, but the text and album art that typically display are gone. I have to then unplug and replug my iPhone to restore them. The whole point is to keep your hands on the wheel, and it takes two hands to disconnect and reconnect your phone.

 

9. Decrease the sensitivity slightly for the scroll feature.

 

When I strum the screen to scroll through Pandora, I can't do it with my fingertip, because it then selects one of the stations inadvertently. I have to instead strum lightly with the side of my forefinger, and then select with my fingertip. Decrease the sensitivity slightly so you have to poke a little harder to select a choice.

 

10. Add consistent iPhone-style navigation throughout.

 

Part of the time, you can browse by finger strumming; other times you have to select a number, or other old-school navigation tricks. Bring the nice modern navigation to all of your menus.

 

Hope the above wasn't too harsh, but hey I love the unit, and just want to see it excel on all fronts.

Yeah...some of these are good. All good thoughts, really. However, a lot of the VR-related issues you cite are a matter of degree, I think. It's hard to classify SOME of these as the basic, simply "DUH" head-slapping mistakes/fixes of the type I allude to in the subtitle of this thread.

I think the one about defaulting to the current city and state is an obvious and simple fix.

I'm an environmentalist, so I prefer NOT having the paper manual...have to respectfully disagree with you there.

The sensitivity thing is discussed in a few other threads (including a post I made...). It's a tricky thing, because RESISTIVE touche screens like this (as opposed to CAPACITIVE ones) aren't really designed for scrolling at all. Pioneer pulled off a bit of a trick getting it to work at all. I concur that it's tricky, however...and have said so in a few threads.

I'll update my list with some of your thoughts and will (obviously) keep yours here as well....it's sort of a second-order list for wholesale VR improvements, rather than a list of straightforward, almost-mistakes they made..., but your thinking is good.

Actually the Pioneer Pandora Link is no longer needed. Just use the Pandora app on the phone.

Right...but he has to have the iPod connected to the cable. If he just launches Pandora on his phone and tries STREAMING the audio using Bluetooth, he will NOT get the album art or song information. That's the key point, yes?

Hey guys,

I just bought a 920BT and will be having it installed tomorrow. I am trying to figure out acouple things.

Currently see in the manual that there is an option to listen to music thru Bluetooth which I think is very cool. Since I use my Blackberry as on of my audio sources. Will the Bluetooth Audio show Album Art?? Or just all the Song info but not bring over the Art.

 

If that is the case then I will spend the money and get the Ipod cable and use my Ipod as my main source now in the vehicle instead of my Blackberry.

 

I just hate carrying both my iPod and Blackberry everywhere I go.

 

Cheers

No. When streaming Bluetooth audio from a smartphone to the X920BT (e.g., using the AVRCP or A2DP Bluetooth profiles), the unit will *NOT* display album art and it will NOT display song information.

As you already know, if you have an iPod, all info and art WILL be displayed. Also, if you use Pandora and install the "Pandora Link" application on the iPhone, I believe you WILL also get the art and info. There's a ton of threads with the details elsewhere in the forum...

sigh

 

the only thing about that is that the software that does that negitively effects sound quality, as it usually doesnt boost quiet music, it usually attenuates all music over a certian level, which can make music that changes drasticly from quiet to loud a lot, sound real bad and uneven

 

It should be an OPTION that one can toggle on/off in the AVIC menus. Doesn't have to be mandatory.

You used a sound meter for your tests, by the way? Wow! Which model?

no it does not (or at least it does not do a good job doing so) as with my ipod the volume jumps all over the place with different songs

 

 

 

i just went out to my car to test this, and with my F900 and my 5th gen Ipod (Iopd video) it does not overide any of the Ipod's EQ settings, it actually "adds" to them. what ever your Ipod's EQ settings are set to will get sent into the AVIC exactly the same as a set of head phones, then the AVIC will adjust the sound again according to its EQ settings

 

 

your sure right there, it looks like its going to come down to where you would like it to sound better, with head phones or in the car, and then just leaving it set that way

 

 

 

i dont know if that has changed with any newer Ipods or the Iphone, but at least the older ones do not (even though it definitely should)

Thanks for testing this!!

Assuming your test results are correct, this does indeed suck. The Pioneer SHOULD have been programmed to automatically level the sound across songs, regardless of whether the iPod's 'Sound Check' feature is enabled. And it SHOULD have been programmed to apply only the AVIC equalizer, ignoring the iPod's settings (assuming that's possible). Adding on to the iPod's EQ is plain silly. As you point out, the EQ settings one would need for headphones in the gym are totally different than what would need in one's car. If you forget that you left your iPod EQ set to something when you plug it back into your car, the two EQ's can be fighting each other....dumb. Maybe they'll read this and include a fix in a future software update...

Thank you guys! =)

 

I did look at page 174 prior to this thread, but I don't believe it tells you what the bars are.

Dude...are you joking? Do you understand the basic purpose of a graphic equalizer???

The whole point is to let you to adjust the loudness of different frequencies of sound relative to each other. The different bars are the different FREQUENCIES of sound! What else would the bars be?? Are you kidding?

The leftmost bar is the LOWEST frequency band of sounds (low pitch...bass, like drums, low pitched intstruments, bass guitars, etc.) sounds you can control, and the rightmost bar is the HIGHEST one (high pitch....treble...) you can control. Each bar in between is a different frequency band of sound in order from lowest to highest.

You do understand the concept of FREQUENCY of sound, yes?

Who are you really? This has GOT to be a joke, correct? You're just trying to see who bites on this practical joke, right?

Hahaha...very funny. I guess I fell for it...this is embarrassing. Oh well.

As far as I know the audio that passes through the dock connector on the ipod bypasses the internal EQ altogether.

You do mean the iPod's internal EQ, right?

Another option, if you only need the pins, is part #181673 from Jameco.

http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&productId=181673&catalogId=10001&freeText=181673&app.products.maxperpage=15&storeId=10001&search_type=jamecoall&ddkey=https:StoreCatalogDrillDownView

 

I just crimped a wire onto the pin and inserted it into the socket next to the mute wire/pin.

Yep...another good call!

Much better than all this cutting of harnesses with razor blades and trying to re-use pins that aren't really designed for multiple removals...

All:

The old D3 manual implied it automatically adjusted sound levels across files on an iPod and recommended keeping "Sound Check" turned off in the iPod for that reason. I was never sure it actually WORKED, however...so I generally kept it turned on....

Questions regarding the newer units:

1. I don't see anything in my buddy's X920BT manual that says anything about this. Do the new units automatically adjust the sound levels across songs? I don't think so based on our experimentation...but we're interested in other opinions. Anyone?

2. Do the X- or Z- units' EQ settings *OVERRIDE* those in the iPod when it's connected? It would be a hassle to turn off the iPod's own EQ setting everytime you take the iPod from the AVIC to the gym and vice versa. The manual on page 172-4 is very confusing about EQ settings, but definitely doesn't say anything about this that we can see. Anyone?

SLA should only be used to level out different inputs. If you are listening to your IPOD and go into SLA you will notice you can set it different fom XM, etc. The only option not avaliable is FM. The point is so you do have large volume changes when switching sources. If you are cranking it up to get more power you are also adding distortion to your system. Loud is just the interan power on the head unit. Can be used it is not the cleanest power but on low or med it can make up for some small amp issues and not trash your sound quality.

P.S. The reason FM isn't available is because SLA adjusts all OTHER sources relative to FM...FM is taken as the "standard" level by the AVIC. So you can make XM stronger or weaker relative to THAT, for example.

Dude...go to basicradiofacts.com and basicsciencefacts101.com

Also, manual, page 174.

All:

UPDATE: Not sure if some or all of these suggestions will be part of the firmware update to the X920BT and Z120BT that Pioneer has promised on their Facebook page....probably. Let's hope.

I think it's time for a new sticky thread that lists all the simple things Pioneer could do to improve the uner interface and experience on the AVIC X- and Z- Series units. I'm hoping the Admins will make this sticky. Don't know how to do it myself...

Anyway, I don't mean this thread to unclude requests for significant new FUNCTIONALITY, or fixes of SIGNIFICANT problems, per se. Those should be covered by topic-specific threads in this forum...

Rather, there's a TON of plain silly little things that Pioneer did that make no sense in the user interface (UI) for the latest units. These are things that could be easily corrected with a firmware update. Some user testing and feedback might've fixed all of these, so consider this a user feedback thread to Pioneer, if you prefer.

Here we go...

000. Show XM Station Logos Even if User Hasn't Hit "OK" to Safety Message:

An obvious bug they should fix...the XM station logos in the preset bands in the AV Source screen don't show up until a user has acknowledged the map safety warning by pressing "OK" on the map screen. Why? Huh?

00. Add Bluetooth Connection Icon to AV Source Screen:

Why do users have to switch to the map view to see if their Bluetooth phone is connected??? Add the icon to the AV source screen. Also, see #6 below.

0. Let Users Type Lowercase Letters:

Come on, Pioneer! Are you kidding with this? We can't use lowercase letters when editing place names in the favorites, etc??? Really?!?!

1. Scroll vs. Selection Beep:

Remove the selection beep when one is merely SCROLLING on the screen (e.g., through playlists). It makes users think they've made a selection instead of just scrolling (or vice versa). It's intermittent, but truly annoying. Also, it's already tricky enough to know how quickly to "swipe" to start a scroll without inadvertantly selecting something on these units. Making sure that the beep only triggers when one has pressed long enough in one location for a SELECTION 100% of the time would help "train" users how to scroll vs. select on this unit.

2. Muting Options:

Allow users to change the amount of mute that occurs when directions are being read on a SOURCE-BY-SOURCE basis. Right now, the units force the mute AMOUNT to be the same on ALL sources. Yeah, they at least let you select either Guide/Phone/VR/Phone vs. just Phone/VR muting (or whatever), but one is forced to apply either total, 10db, or 20db as the SAME mute level used for all sources. Bad interface design. Some people want total muting when a phone call is active... but almost NO muting when playing XM.

3. Make Arrival Data Button Work As It Used To:

Restore Waypoint AND Final destination arrival data to the little timer/distance/arrival cycling button in the upper right of the map screen. Right now, one has to go into the route overview to see final destination arrival data for a multi-point trip. On the D3, there was a little button on the map screen in the lower left corner that used to let the user choose between waypoint and final arrival data. This is a real annoyance...one can be on the phone and be asked when one is arriving at the final destination. Right now, all one can say is "well, I know I'll be at the gas station first in ten minutes...let me fiddle with my screen while trying to answer your question..." Geezuz.

4. Group ALL Sound-related Options in Same Menu:

There are three different menus relating containing sound options (Two different AV menus, and the system options that include the master Volume sub-menu). This is no non-intuitive, it's ridiculous. It's really annoying that AV and volume related controls are scattered across three different menus.

5. Restore The Button to get All AV Options to the AV Source Screen:

Yes, one can get to the "EQ" directly from the AV source screen. However, unless we're missing something, one now has to go to the Home screen, into Settings, and then into one of the AV Sound options to change the settings to change the staging, LPF, Loudness, etc. Same thing for Staging! Now, one CANNOT get to the "Staging" menu directly. Why?? What if I'm listing to a playlist with some classical music and I want to use Dynamic Theater....and then I switch to Rock, for which I want the Music Studio staging? As it stands now, a user has to go the main home screen, then into Settings, then into AV....then...WTF, Pioneer?!?!

6. Make Bluetooth Connection and iPod Album Art Icons Non-Microscopic:

Why, in the name of all that's holy, did Pioneer make the Bluetooth connection icon on the map view INSANELY small? It's like...ten pixels across, which is hard to see in a brief glance while driving to insure one's phone is connected. What the hell? Seriously...what the hell? It should be at least half the size the iPod album cover shown on the map screen in the lower right.

7. Neatly Align Song/Artist/Title Info in Sound Info Bar at Map Bottom:

What's with the apparently random decisions about how to align these in the song info bar that one can open/close at the bottom of the map screen??? And why not use the same little artist/album/song icons they use on the AV source screen to help us quickly interpret which is which? And why not use the same order here as on the AV source screen itself. Just plain sloppy...two seconds' thought on the part of a Pioneer software programmer would've helped here.

8. Scroll ENTIRE XM Song Titles, Artist, Etc.

We're into the fifth AVIC product line in five years and we STILL can't see entire XM song titles? Really, guys? in 2010?? Support at least 32 characters of XM song data, please...if not unlimited...come ON!!! Seriously??

9. Scroll ENTIRE FM Station/Program Name & Remove Silly 'PS:' text

Why so few characters for FM station/program names? Why scroll with only about ten characters instead of using more characters? Why place the needless clutter text 'PS:' in front of the station/program title?

10. Stop Cutting off "My Mix" Song Memo Text.

Self-explanatory...please show the ENTIRE Memo text, including both song and artist, in the list of "My Mix" memos so you can go buy the music or look it up later if you want. They've been cutting the text off -- and not displaying both artist and song -- since the D3. Why? What's the point of not letting the user see the entire memo text until it happens to be playing live on XM? How can you decide which "My Mix" song memos ones to delete or turn off/on if you can't read the titles/artists later on? Just plain idiotic...

11. Allow Users to Add Route Cancel as Quick Access Selection Button on Map!

Right now, if your passenger wants to cancel a route while driving and looking at the map screen, he/she has to go Home-->Destination-->Route Cancel. Why can't one add the Route Cancel button to quick access menu on the map screen?? Didn't the D3 at least offer that?

12. Bring Back the TRFC Button!

There was a TRFC button on the AV touch screen in the old D3 that you could program to instantly bring up whatever traffic station you wanted to associate with it (e.g., a local FM station, XM's audio traffic and weather station for your region, etc.). Why'd that go away? Bring it back?

13. Don't Change AV Source to iPod Just Because We Plug it In!

Someone putting their iPod back after using it in the gym doesn't necessarily want to make it the current AV source...especially if we're listening to a critical news announcement on XM or something! Stop this! Or give a setup option to choose this.

14. Default to Current State/City When Searching for POIs

15. Change Spelling of "Judgment" in Safety Caution:

In American english, "judgment" is correct....in British english, "judgement" is correct. But in LEGAL circles, "judgment" is ALWAYS the preferred spelling.

I think I've come to that same conclusion. The green/white wire is used on the SWC (if you have them). Thanks for the help everyone.

I can't accept that conclusion, and believe it to be incorrect.

Is everything WORKING the way it is now? OnStar volume up/down is working? What is NOT working?

Hmm...I wish you had said which one you meant in the original post! There are two green/white wires coming from the OS-4...!

Anyway, so I'm sure you already saw that the OS-4 instructions say that the green/white wire on the OS NAV connector is the "OnStar push button volume adjustment input"...

So...first guess is that you're supposed to just find the wire on the Tahoe-side where the On Star push button volume input comes off the steering wheel and wire it to that wire? Not sure yet where to find that...

I found a few posts of people who have taken off the steering wheel shroud in 2006 Tahoes to get to the SWC harness, but haven't ID'ed the correct pin or connector for you yet...assuming it's a Chevy harness you have to go directly to.

For example, here: http://www.tahoeforum.com/showthread.php?t=15561

Or, you may have to wire this to one of the connectors on the Body Control Module (BCM, that's where the Soundgate version of the SWI-PS wires to...see HERE).

Or, perhaps it goes to the OnStar VCIM module?

However, it may be you're supposed to wire that to something on the SWI-PS....hmm. Will look at it again later...

Dude...

It took a little review of all the install material, but from what I can tell, you're not supposed to connect the green/white wire to the AVIC at all...I think that's why you can't find a place to put it.

Question #1: Is the green/white wire you are referring to the one coming FROM pin 17 on the OS-4's connector named "OS-RADPWRAUDIO" in the install guide (i.e., the connector where most of the other wires go to the AVIC)??

Question #2: Do you have steering wheel controls in the Tahoe?

If your answer to BOTH questions above is YES, then you're supposed to be using a steering wheel control interface such as the SWI-PS with your vehicle. The green/white wire goes to the SWI-PS...

If the answer to question #2 is NO, then you're supposed to wire it to a new single-pull, single-throw (SPST) switch you can put somewhere in the car (i.e., in place of an existing On Star button?) -- or wire it back to the existing On-Star switch if it's SPST.

Thanks for that diagram but I've already looked through that. I know where every wire goes from the X920BT (i.e. 4 speakers, VSS, reverse, parking, etc.). My question specifically relates to the green/white Onstar wire coming from the PAC OS-4. What does that wire connect to on the unit? I don't see any green/white wires.

Hmm...I spent a few minutes Googling, and think I found guys who did pretty close to what you're trying to do...if not exactly.

First, I presume you have the OS-4 wiring instructions that came with it, right? I mean these....they seem to say the green/white wire goes to the steering wheel control (SWC) output.

http://www.pac-audio.com/PACProductData/OS-4/1_Instructions/os4_instructions_102910.pdf

Also, I think you already talked to this guy on these forums, right?

http://avic411.com/index.php?/topic/28998-another-z120bt-tahoe-install-threadlol/

Anyway, here's a guy who used the OS-4 in an Enclave and says he had to wire green/white wire directly to the "BCM" in that vehicle?
