Help!

I borrowed my friend's accord 2009 nav DVD and put it into my 2006 Accord. My nav automatically updated itself using that DVD. I have returned the DVD back to my friend. And now, my nav won't take my old/original DVD anymore. Does anybody know how to reset (backrev) my nav?

Thank you in advance for your help!

Not sure if it's possible. Your owner's manual probably specifically states not to do exactly what you did.

I figured it out. Pressing Map, Menu, and Cancel buttons for 5 seconds brings up the hidden menu. I tapped on Version and then Download. My system downloaded the system from the original DVD... and the problem is fixed.

Thanks for the advice!!! It worked on Honda Odyssey 2006. How did you figure it out about backrev? Very impressive.

bring to the dealer, maybe they can reprogram it.

Great advise but I tried to avoid just that. Later, I have seen this triple keys (Map, Menu, and Cancel buttons) in many messages but this one from cobre was the first one and was the solution for my problem.

I tried to load Honda NavDVD that I have burnt from torrent and it did not work. I have tried 4.73 and 4.63. Both of them give errors. No luck and I could not find anything definitive on this forum and anywhere else.

it doesn't work at all or just no sound?
