Car Won't Start Without Factory Stereo
I have a 2006 G6 with stock stereo (not Monsoon) and no On-star. I'm trying to install an aftermarket stereo using the Metra 99-3303 kit. I seem to have it hooked up properly (stereo works fine), but the car won't start. Lights, remote door locks, wipers, etc work fine, but the engine doesn't seem to even turn.
If I pop out the aftermarket kit and put the factory back in, it works fine. As soon as I unhook the factory stereo, I can't make the car turn on again, even without the Metra kit hooked up. I was under the impression that the G6 should work even without the DIC hooked up.
Crutchfield tech support was stumped too. Their best guess is that either there is some sort of security lockout (I don't have an alarm system, though) or that the Metra was bad, although, like I said, I thought the car should work with no stereo or DIC at all. Does anyone have any ideas?
Thank you much.
