I have a 06 cobalt as. I tried to put a after market headunit the other night but when I hooked the factory wiring harness into the new radio it blink The security system and now i have no radio. I put the old one back in and nothing. I checked every fuse the car has and tried disconnecting the battery for 10 mins but still no radio? Any ideas? Thanks

probably wrong harness and sent something up the GM lan wire... does the stock radio not turn on at all or just no sound? also anything else electronic giving problems?

the factory radio does not work anymore. the door chimes are still working but no radio, the radio is not showing anything
