Just bought the car today, the stock head unit doesn't work, figured no probelm, probably just a fuse or wasn't hooked back up properly when someone was selling it.
The fuse is good - there isn't one on the back of the unit itself. And it was hooked up right. I actually don't think it was ever switched out. So my thought is the unit is junk. But here's the problem. I'm not sure what the extra wires on the back of the unit are for? I know one is for the radio. They can't just be unplugged, they'll have to be cut.
I've looked online for a wiring diagram, but haven't had any luck. My only expierence with this stuff is with my Pontiac which is WAY different. I just don't want to cut something that I shouldn't.
