I have had this problem before but it has been so long since I have messed with my head unit.
Alright one day I was bored and thought I would change my gps on the map to a car instead of the little pioneer symbol.
My head unit pooped up saying it couldn't find the picture file and then rebooted. Now it is in a constant boot every 3 minutes.
I was using some mod but I dont remember which one the only thing I remember installing was the ipod theme.
I was wondering if I could just delete everything off of the head unit and reinstall the 3.0 software or just reinstall 3.0 over top of what is already on there.
Like I said it has been so long since I moded my unit I cant find my backups of my original software just wondering which would be the best option
