Help! My AVIC-Z2 is dead. When power is applied (accessory) the cooling fan runs and that is all that happens...no lights, no functions, nothing. I sent this unit to Pioneer service, they sent it back, with an invoice stating "checked all functions." It worked for a week and then went dead again. It was working fine, stopped to get gas, started the car and NOTHING from the unit.

Do any of you have any idea what's happening here? The unit is installed into a C-5 corvette. It has bluetooth, CD changer, and XM connected to it.

You'll probably get more feedback if you posted this in the AVIC-zX section (this is the XM satellite radio section). Just a guess, but it sounds like you might not be getting enough power to the unit. These units have to have enough power to start, i.e. it might not be getting a go enough 12volt current to get above the threshold. I'd recheck the power connections, both the yellow and red. I've also heard that GMs have some funky power issues that can give these units some troubles.
