Anyone seen this message? I used a DVD cleaning disc multiple times, but no luck. The Nav disc was purchased from a member on the site.

These are the messages I receive.

Incidentally, the original DVD that came with the car does work.

The vehicle is a 06' 750Li
Thanks!

If the DVD is in the Navi unit then it looks like you need to replace the laser lens in the Navi unit itself.

You can send the unit out for repair if you are unsuccessful at attempting to replace the lens your self.

If the old disk works but the new one doesn't, I don't think you need a laser repair. After thinking some more about it, you might need to upgrade the firmware to use a more recent disk. Look for the v.32 firmware instructions - I think you can find them in the DIY section.

most copies dont work, use an original disc.

Ok, went to Tom Bush BMW in Jacksonville to purchase the firmware update that this site says can be had for $10. Not according to Tony, their "expert". He will not sell the update but will install it for 1 hour labor, or $125. Nice...btw, the links in the firmware upgrade instructions don't work, so I'm unable to burn a CD. Is the upgrade disc available for purchase elsewhere? Thx
