I grounded:

 

1. The Unit (black wire)

2. The Parking Brake wire

3. The relocated Mute wire

 

All to the vehicle chassis (ground).

 

Works perfect.

I have done all this. I took my radio out 5 times to recheck all connections. It works, but when I start driving, I get the p brake lead message or w/e it is and then half my settings are gone and song labels don't show and stuff and until I come to a stop, everything is enabled. This leads me to believe that my unit requires both grounding and hacking the software. I have NO idea how to do this, so can someone PLEASE tell me how to hack my radio step by step, and not just say "data.zip"

Like everyone else who has had this problem, and swore up and down that they did it all right, you have a problem with the grounded & relocated mute wire. Almost certainly, you damaged the small fragile contact when you moved it. That's all there is to it.

Hmm that's one thing I didn't try. Maybe the pin isn't in all the way and not getting a full contact. I'll take a look at it again tomorrow and see if that works. I really hope so, because I grounded the wires 10 times so that cant be it.

Hey guys,

First I apologize because my english is probably awful

So i bought the AVIC F910bt, i didn't not installed yet.

I understood how the hardware bypass works. There are two steps :

1. Move mute wire as indicated in first post in this thread : i follow this instructions and it's done >

2. . Ground parking brake wire : I'm a bit confused ;

Ground is the black wire right? Shoud i cut it to connect to the parking brake wire?

The parking brake wire has something red..I don't know what is it, and if i have to cut it.

Thanks in advance.

That is what you use to tap that wire into the other wire. In this case, you will tap the green wire into the black ground wire. You will need to purchase a separate tap for the mute wire. From what I understand however, EU units don't require the mute wire for the bypass to work properly so you may be able to skip that step. Try it without it first. If it doesn't work then connect it as instructed.

Ok, so i have to cut the black wire and to tap it to the red thing. Thank you.

No you don't cut the black wire. Just tap the green wire to the black wire.

Thank you. I'm still waiting for my fascia and the Steering Wheel Stalk Adaptor... I will let you know if everything is ok.

To all those that haven't done the bypass yet...I let the installers hook everything up the proper way. Then after reading this thread from the start I located the parking brake (green) wire. I didn't even have to pull my dash apart as I was able to get to it from underneath the driver's side dash. I cut it there and grounded it to an existing ground which happened to be right there near it. Then I did the software mod by changing the setting in the data.zip folder from 16 to 256. My bypass was easy and works perfectly!

I know this post doesn't explain exactly how to do the software mod. My intention was to tell you what method I used and just how easy it was. I won't pretend like I didn't read a LOT before taking this on and I will say that all of the answers are here. It's like any project...measure twice, cut once.

Thank you everyone on here for creating and adding to this awesome site!!

OK let me get this straight. After I move the mute wire to the new location. I need to tap the parking brake (green wire) and the newly relocated mute wire (yellow) to the ground wire (black) right?

i think i'm missing my mute wire. i bought my unit refurbed and the a/v harness doesnt have that yellow wire

Yea your missing that wire. You need to contact the place you bought it and tell them your harness is incomplete. Tell them you will need that mute wire to connect an OnStar interface.

say I have a second pioneer harness for a regular single din, would I be able to pull a wire off of that and use it in this harness? if the place I got it from won't give me a new av harness

If the wires are the same size you should be able to swap a wire from the other harness.

I installed my avic F7010bt last night into my 03 suburban with boes and onstar, and tried to do the bypass but ran into a problem. Because I have boes and onstar I had to get the gmos-04 and got the aswi-ps for the steering wheel controls. I haven't hooked the steering wheel control up yet, so here is where I'm at... The GMOS says to hook it's ground to the avic's ground so I put the gmos ground,the avic ground and the parking break ground all on the same ring connection. Then I moved the mute wire as shown at the beginning of this thread and put it on a ring connection. I put both rings together and ran a self tapping through them into a metal bar that runs vertically right behind the unit. When I did this and turned the unit on it was muted and I couldn't figure a way to get that off. So I took the mute wire off the ground and regrounded the other ring and everything works except I get the parking break error message.

After going back and looking at it again I realized that my units wiring harness had the mute wire in the right place from the start and that I moved it back into the standard mute location when I tried to move the wires. The harness was in a sealed package when I opened it so it's pretty weird that the wire was already moved. I guess I just assumed that if it was in this slot when i opened it then it must be getting moved to the other slot for the bypass. Moved it back and grounded it and now everything works great! Thanks

I searched... I really did!

I have a PAC harness (c2r-frd1) that I have used to connect my X910BT to my factory clips in my 05 Mustang. Searching the forum says it should work however it didn't answer my question.

Do I connect to the PAC harness as if I wasn't doing a hardware bypass and then ground both pb wires (the one from the harness and the one from the deck)? ... or do I not hook up the pb wire to the PAC harness and just ground the pb wire from the deck? The mute wire is a non issue as there is not a matching mute wire on the PAC harness.

Right now I have the pb wires connected together and grounded and the mute wire moved and grounded but I get a pb error like mentioned many times.

Yes, leave the wire from the PAC unconnected and ground the parking brake wire from the AVIC. This has been covered at least a few times in the forums.

You also do have a mute wire issue. That's why you're getting the parking brake error. You only get that error if the mute wire has not been moved to the correct location and then grounded.

Did you move it to the proper slot in the connector to the AVIC?

If so, then you damaged the pin in the process and it is not making contact with the AVIC. Pull it out and fix it.

Yes the mute wire has been moved but I may have damaged it in the process. The first time I tried I could not get it in all the way and I bent it. I was able to straighten it out and it snapped into place but perhaps it is still not making proper contact. I will check this out tonight and I will also disconnect the pb from my PAC harness.

Thanks for your help!

hi Guy's, i moved my mute wire and grounded the parking brake wire and i DO NOT get any error messages but my music video's do not play from my SD card although the sound is there with a black screen? Anyone have any ideas on what is going on?

Thanks.

Mute pin was not damaged so all was good there. I separated the pb wire from the PAC harness and voila, worked. Thanks for all the help. Now onwards to trying some of these awesome mods that are on the site!

Thanks for your help joegr!

Hey all, I'm new to the forum...

I'm going to have Bestbuy install this radio for me.

My question is....

I can't seem to get a good understanding of what needs to be done to the unit before you can drive without restrictions.

I need to be able to print out a guide in order of what needs to be done so the installer can do it while reading the sheet.

Is there something I need to do software wise as well?

WIll this bypass make it so you don't need to do anything additional to the unit when it boots? Just use it normally without restriction?

I haven't bought the unit yet.. Most likely I'll get one for $500 on ebay from a seller that sells refurbs.

Need some help here, I had the software bypass in place and once I upgraded to the 3.? version I started getting the parking brake wire warning box. I decided to do the hardwired bypass and open the dash to start and found I have no open slot to move the yellow wire to and it looks like the yellow wire has been spliced into another wire as well.

Also the blue wire is looped into two slots... normal?

You're looking at the wrong connector. The connector you want plugs directly into the back of the AVIC. Go re-read the start of this thread.

ok so ill be getting my x910 soon, and i know this is the bypass for that as well. but on the first page, the instructions only say to move the mute wire. my question is after moving the mute wire, which wires do i ground or connect to other wires?
