I have a 2007 hummer h3 I changed the cd player in, when I did I unplugged the plugs for the four ways, push button 4x4, and heat/air controls. When I hooked everything back up and plugged everything back in the h3 wouldn't start and the ignition locked up. Is this a theft safety feature? If so how do I fix it?
Do you
have the same problem?

You put the original radio back in. GM got you too along with all their other unsuspecting owners with the tricks they design in to bleed money from you after the sale. In an attempt to lock up all the repair business for their two grossly over-priced repair centers, they stopped selling us radio service manuals after the '94 models. In response to the typical $450.00 bill to repair a cassette radio, people bought nice aftermarket radios for one third that cost. To combat that, GM built the Body Computers into their radios so they can not be removed. You must get it fixed.

Look for a "radio relocation kit" for your vehicle. That will allow you to mount the original radio somewhere else, and just cut the speaker wires and run them to the new radio. You won't have the warning chime function but the Body Computer will broadcast the turn-on signal to all the other many computers, and all the systems that never needed computers in the past should work.
Was this
