i was sitting in my truck listening to the ipod touch through my avic d3 with the key in accessory mode, i turned the car on and then i got a a message on the screen that says "An error has ocurred Please turn power off and on again" and it comes on powers off and comes on again and I can't shut it off like it says. Please help!!!

I'd try disconnecting your battery then hook it back up and try it again.

I tried that and no luck. At one point it asked to insert appropriate disc, so I inserted the nav disc and then it just brought up the same error

Did you try the rest button ?

I've reset the unit with the power on and off and still no luck. I sent the unit to pioneer warranty center in long beach and they couldn't duplicate the problem twice now. It's really starting to piss me off. the install is good, I've tested for power spikes in the remote, power & accessory wire, the grounds are good....?
