Ok I've searched and searched and I can't get a straight answer. I need to know what wiring harness I need to install my double din radio. I don't care about onstar, the DIC, steering wheel controls. The only I care about is the remote start and keyless entry. Will I lose those functions? I just want to install the radio and go. I have a 2006 G6 GTP with monsoon. I just need to know what the part number for the wiring harness is. I can't seem to find one. I'm on a strict budget that's why I'm not getting the metra double din kit with the DIC. I can't afford 200 bucks for a dash kit. I just want to pay like 30 bucks for dash kit and harness like I have in the past. Any help will be greatly appreciated.
