i just removed the aftermarket dvd unit out of my 06 hummer h3 and installed the factory one because i was suppose to trade it in today but now the car wont start. i tried to get it towed but the it wont shift into neutral! i dont know what to do anyone have any ideas? there is also a black n red wire coming from the steering wheel, and a black/white wire and blue wire under the dash that have been disconnected by my brother and he dont remeber what was hooked up to it. there is also a black wire comin from the computer that the installer has that is not connected under the dash.

By dvd unit do you mean the radio? Did you remove the interface that was likely installed for the door chimesto work? Try removing that.

well i had this problem for like 3 years now with the pass lock. if the pass lock is flashing i have the answer. i called the company thats has the security of the hummer and they told me that to make it sync with the key and never have this problem again you have to on for 30 minutes then of for 5 minutes and repeat 4 times. i solved my problem. good luck with yours.
