So.. my battery died last night, and I was jumped. I have done this several times. After the jump my Z1 displays the black "Starting Pioneer Car Navigation" screen and then the blue Pioneer screen. This screen stays on for about 10-15 seconds, and then it reboots and does the same thing over and over.

 

I have tried holding "Map" but nothing works. I have also tried doing a front panel reset.

 

Does anyone know what could be wrong? Maybe the software was corrupted?
