    I just installed a head unit i n my 06 and when I got my wiring harness I was asked if I had onstar, I was told that there are like three wirning harness' for the GM trucks. One for onstar one with the door buzzer and one without anything. I had to pay like $70 for mine with the door and seat belt chime. And it's louder than the factory chime. I'm not sure about remove the onstar I've never heard anyone doing that. Good Luck.

    So there is no way of using an aftermarket head unit with out buying that onstar bypass? i thought that was only if you wanted to keep onstar using an aftermarket head unit?

    here's what you do: there are TWO harnesses that plug into the factory radio. one of them is the conventional GM plug that has power / antenna / speaker connections...and the other is a tiny connector with like 4 or 5 wires in it. in the tiny connector with 4 or 5 wires, there is a pink wire. if you run the blue/white remote output of the head unit (or the RED wire if there's no blue/white) into the PINK wire of this harness, your sound system will fire up. this is the factory amplifier turn-on wire. i've saved people bookoo bucks doing it this way tons of times.

    similar head unit problem in 02' Tahoe

    I installed my Pioneer DEH-p3000IB head unit into my 02 Tahoe and it will turn on and light up like it's working but there will be no sound from my speakers. Sometimes if I turn my electricity on it will come on, but if I turn the car all the way on it will still act like its working fine, but with no sound. It will work fine sometimes but most of the time it doesn't put out sound. The people at BestBuy said to buy like a 70 dollar wiring harness for it to be able to work with the OnStar, but I'll probably try your method first. Any more advice?

    Dont buy car audio from Best Buy, it is expensive and the product the sell for harnesses is JUNK! Cant remember the name for sure its like Dynex I think.

    did that work?

    Did the advice that guy gave you about running the white/blue wire into the pink wire work? because I have the same problem in my 02' Tahoe

    If there is a wiring from remote out to pink wire works, this is the best way. If i am not mistaken, the 02 gm trucks have the non-upgradeable analog onstar that you cant use now if you wanted to. So my view, although i do not have onstar is thisL

    why pay for a harness to retain a feature I couldn't use if i wanted to?

    does that concept seem a bit weird to anyone else?:lol:
