My Avic F900BT when connected to power the Dial and buttons light up for a few seconds then go out. The screen doesnt light up flash or even go to the splash screen. Its got power because you can hear the fan running. IS it DEAD ??? Im sure its a software issue because it was a 2.0 unit and someone tried updating it to 3.0. Can the unit be flushed and redone with the 3.0 ? Is there anyone that can reload everything or does it have to go back to Pioneer ? Any Idea of costs to do so ? I would rather pay someone to fix this since I am not great with programming.
