I just recently tried upgrading to the 80mt disks. It did software upgrade and then said please eject and insert appropriate disk. Kept getting that error so I went into the reset menu and followed the instructions that were posted in this forum to downgrade back to my 60mt series original disks. After trying these steps it still asks for me to eject and insert appropriate disks. Any suggestions out there our is this need to be sent to pioneer?

send it budd, you bricked your unit just like i did , needs a reflash and maybe a part that sometimes burn .. ( im waiting on mine back right no)

The disk on the this site bruned my UNIT (AVIC N4) Caution to anyone downloading the disks! It will costs you more than the $120 for bran new disk! Don't reck your unit for $100 like I did!

HI I HAVE THE SAME PROB...I HAVE A N3 ON 70 MAPS (BURNED COPIES) (I DONT HAVE ANY ORIG DISCS.) AND NOW IT SAYS "please insert appropriate disk" SHOULD I PURCHASE THE 80 DISC AND TRY OR WILL IT RUIN MY UNIT? THANKS ANY HELP APPRECIATED.
