I have an AVIC-80DVD unit and the disc is very scratched up and wont read anymore. I also cant make a backp of it because it wont read in my PC. Does anyone have an iso image of the CNDV-50MT VER 1.2 EAST disc that I can download and burn or if someone could burn me a copy and send it to me I would be willing to pay you for it. Thanks!!!!
