Thanks for the help...I got the radio out, checked the connections, put it back, and it's doing the same thing., which means sometimes it asks for code, sometimes not (which means it doesn't run, or if it does, for just about 1 minute).
When I was checking the connections, I wasn't quite sure what I was looking at. I'm ready to go deeper into the problem, or just get a new unit.
Do you think that it's just the HU. I'm really hoping it's not the car.
Thanks in advance to anyone who can help,
