Good evening,

I have a AVIC-920BT that i bricked a few years ago. I was trying to copy the boot file and i acidently pasted it over itself. When booting the unit, the screen says "Thers is no applicaton software" but the backup camera still works. I can put it into test mode and see all the files but i will need a new file to copy on to the unit. Anyone have any ideas?

Several. What file did you clobber?

Have you tried switching to the reserve program directory? Does /USER/PRG.FLG exist? If so delete it. If not create it.

Have you tried installing the latest software (v6 2015 maps)? 

RonS; how can i download (v6 2015 maps)? Could you leave here a link address? Thank you.
