LV_H2

My installer went with the Scosche adapter with the PAC-SWI for my 2007 H2 and it works great. I added the BTB200 afterwards. http://www.scosche.com/scosche_caraudio ... goryID=228

Bullseye, I did confirm that with the Scosche adapter and D3 in my H2, I DO have front/rear fade control. I did not do the initial install myself (only the bluetooth afterwards), so I don't know the specifics of how my installer wired the set-up. Good luck.

Dash & Center Console removal instructions: http://www.elcovaforums.com/forums/show ... emove+dash Not that difficult.

I have the D3 in my Hummer H2, but with the Scosche adapter, and I am pretty sure that I have Front/Rear Fade intact. I keep it at about 6+ towards the Rear speakers. I'll confirm today and let you know for certain.

Thanks Shotgun. I was looking for it in the A-pillar, and couldn't find it as a separate set of wires. By that point it was tightly bundled and packaged with other wires. It makes sense to get it at the running light, I actually had that grommet out to see if I could back trace the wires! Any way to tell which of the 2 wires is the "hot" one, without first splicing into it and testing? On another note, I was able to run the BTB200 MIC wire through the A-pillar to the ceiling location of the Onstar MIC. The BTB200 MIC wire exits the ceiling at the edge of the Onstar MIC cutout,

I leave my lights set on "Auto" and am looking to tap a source that comes on with the headlights and is NOT dimmed. I had a dimmed source hooked up, and the D3 illumination was reverse with respect to the dimming function (interior light low & D3 bright vs. interior bright & D3 dark)

Do you know a good place to tap the ILL on a Hummer H2? Another member had suggested the wire for the roof running lights in the A-frame, but I was not able to clearly find one there. I have fully installed and ran the ILL wire (disconnected) to below the steering wheel where I can access it easily. I am hoping for a connection somewhere near the fusebox to the left of the dash with driver door open. Any suggestions?

Yes, as stated, you can leave your NAV disc in permanently and use Navigation and keep your iPod connected and hear music all the time. You get NAV and Music at the same time. Works great.

Thanks Shotgun. I grew up soldering all connections and really have no experience with all of these "new" connectors. I also plan on looking into the A-frame for the ILL hookup, as you suggested. In addition, I am going to see if I can route the BTB200 MIC to the ceiling through the same cutout as the native Onstar MIC, any experience with that area?

I finally got the Bluetooth unit from Crutchfield, going to install it tomorrow. Question: What is the best way to "splice" into the radio power source to connect the BTB200? I was planning on disconnecting the radio harness, and connecting on the radio side (so that I don't have to disconnect the battery lead). What type of connector would you use to "splice" the power source?

Thanks to both of you. Bullseye, I saw your before and after pictures. Sorry that there are such A$$holes in the world. The VSS was Green/White at the 12 pin connector, in the 2007 it was the "H" location, not the "E". (both are green/white). My understanding is that it is the "E" location pre-2007. I did tap into a "dimmer" illumination source (one of the 4 wheel drive differential locking lights), but connected to the dimmer system, the D3 illumination is REVERSE with the dimmer switch, and less than full in daylight. I mounted the antennae under the dash, dead center and i

Thanks for the info!

Hi All, I had my D3 "professionally" installed, and I am now going to do my own bypass and install the Bluetooth BTB200 in my 2007 Hummer H2. Question: For the BTB200 Power Source: is it OK to "tap/splice" into the power source for the D3, or do you need a direct run to another power location? Also, my installer hooked the ILL wire to a source connected to the dimmer, now i get "reverse" dimming of the D3 versus the cars illumination at night. Does anyone know a "clean" non-dimmer source to tap for the ILL in the Hummer? Thanks all. (P.S.: I did search for these answers fir

Crutchfield has them in stock. I just ordered mine online.

Where you run the excess GPS antennae cord can make a difference!! I just had my D3 installed in my '07 Hummer H2 and had very poor satellite reception. We took the dash apart and all connections were fine. The GPS antennae looked to be situated perfectly, just under the plastic dash, front, center at the windshield. The installed had "draped" the excess GPS antennae cord to the "right", over the HVAC duct, and it was free and clear of any obvious problems. We went out for a spin with the dash off, and simply draped the excess cord to the "left" over the left HVAC duct and suddenly wen

Just got done with my installer re-doing the connection on the AVIC D3 in my 2007 H2. The VSS was obtained from the Factory 12 Pin connector at the Radio. The wire is Dark Green/White Stripe. My 2007 had TWO identical Dark Green/White Stripe at the "E" and "H" positions. According to my installer, the models previous to 2007 had one such wire at the "H" position which should be used for VSS. On the 2007, both are VSS, but the installer was recommended to use the "E" wire. We hooked up the Dark Green/White Strip "E" wire, and it works perfectly. (The installer's assistant did the fi

Thanks for the info. Do you know which wire on the radio harness is VSS? It is the standard factory NAV/Radio which has "speed volume compensation" so it must have VSS at the radio harness.

Anyone have a diagram of the Hummer H2 VSS location/wire? 2007 model (same factory NAV unit as 2006 & 2006).

I tried searching the site, but couldn't filnd it. Anyone with the VSS wiring diagram for a 2007 Hummer H2? Also, any info on day/night illumination? I usually leave the headlights in "auto" mode. Thanks!

Looks great Bullseye. I just had my AVIC-D3 "professionally" installed in my '07 H2, but they did NOT hook up the VSS. NAV is off quite a bit. I will have them re-do it this week. Question: Do you have a link/info on the VSS wiring for the Hummer H2? Thanks.

Hi All, I have a 2007 Hummer H2 with Factory NAV/Radio, Factory Premier Bose, and ONSTAR. I am considering an upgrade to a Pioneer AVIC-D3, AVIC-Z2, or Alpine IVA-W205. I have a question regarding anyone’s experience with the different INTERFACE HARNESSES on the market. I am a bit leery of messing with the Hummer’s electrical interface, as I have already tried a Nucleus/American International iPod adapter and had major electrical problems. There seems to be four different harnesses out there designed to work with the GM Class 2 data bus, retain ONSTAR, retain factory door c
