I have an issue with reading the Nav disks. Every time I put it in it gives me a read error. The disks are fine becasue they worked before with no issues. I can play cds and dvd with no problems, jsut when I inser any nav disk in it gives me an error. Before I could get it to work randomly by inseting it right when the car starts or leaving no disk in for a week and trying then, but now nothing works.

Any thoughts?

Are these copies by chance? When your drive is reading (other) disks are they copies also or originals?

The map disks are backups yeah, and I would think its a bad burn as well, but they worked perfectly fine before, untill I accidently pressed the eject button, at which point each time I tried to put it in, it would say read error. The other dvd I had on hand was a dvd with divx movies on it, which worked with absolutely no issues.

I would understand if it didn't read dvds or other disks, but just the map disks? I'm very confused. I have made fresh copies with no luck, same deal.

The dual layers copied nav discs are fragile. Finger's prints or fine scratches can make them useless. I went through so many of them(I service and sell these units for a living). Go back to the oem disc and downgrade it if you want to avoid headaches. You can almost run over an oem disc with a tank and it would still work. Good luck.

Interesting, just frustrating because they used to work fine, and if i didn't press the eject button by accident I would have been just fine lol. I made a new one to try out and its a no go. Perhaps I need to try a different dual layer disk

SO, I fixed it. I burnt the disk on a different brand and it works NO problem. REALLY odd that it started hating my other disks....anyways, issue solved
