occasionally I get this message on the MMI when I select nav?

sometimes it goes away on it's own....

sometimes I have to eject/reinsert the DVD disk....

sometimes all's I need do is reset the MMI via the manual procedure....

why does this happen, what can I do to get it to stop?

There is a TSB in the library I set up with Dr. Cold. Check the link in my signature.

I had checked the TSB library and none of the conditions apply to my circumstance?

Looks like its time to add a new TSB to the list...
I got the same message a couple of days ago, didn't happen ever since !

Did you look at the 4th TSB in the navigation section that responds to when the MMI screen says please check navigation DVD?

I think you need the firmware update for the nav I have to bought it a couple months a go.

davekr

yes, I went through the entire "check nav DVD" TSB before I posted.

I have had this problem intermittently, the last time it would happen
when I stopped at a specific shopping mall, in warm dry temps as
this shopping mall is away from the water/shore in my town?

it stopped happening for quite some time, and has now returned.

approx 1 in 3 times I use the car/nav it shows "check nav DVD"

usually stopping the car and ejecting/reinserting the DVD clears
the problem, sometimes it takes several attempts?

I see the same with my Q7 ... mmm, please help

I had a similar problem that seemed to be resolved with a firmware update when I initially did my nav retrofit. But that was a "new" installation. In your case I assume you have not changed anything from when the car was new and now 5 years later you are having an issue. I can only figure this is a hardware malfunction. I'd first try a new DVD, then perhaps run a DVD player laser lens cleaner disc through the system, and then ultimately it may require replacing the DVD/NAV reader in the trunk. Good luck.

Question, is it safe to use a CD cleaner (the one with the brushes on the DVD-ROM) ?
