My display shows that Nav disc is missing..its not the case
 

for sure.. i recall it being on earlier in day and then i stopped at a dunkin donuts for a coffee.. i started up my car looked at my screen and on right side(sm window) of my screen i always have nav on..this time it should vehicle info...i then put nav on big screen and it says please install disc..10 minutes later my seat belt was ringing to notify me that i need to lock up my belt.. i had it on..the bell stopped after 5 times...but nav still says samething.. i pulled over and shut off the X.. pushed eject on nav but nothing.. i then tried to put in a regular cd in nav slot but it wouldnt take it...what gives? no way someone broke in and took my disc..i was in DD for 2 minutes and i always look my doors...what gives?

This is a common issue -- the Nav DVD drive is faulty. It will trigger a fault code, the technician will replace your Nav DVD drive.

it works once again... electricial for sure
 

:(

There is apparently a bulletin from BMW on this. Current "revised drive" is backordered so there is a fix. Mine was fine for 11 months and in the last few weeks, virtually everytime I start the car I need to eject and reinsert the dvd. Interesting as one dealer I went to acted as this was such a strange problem and they had no idea what was going on. Dealer #2 said, "oh yeah, we know what is going on", pulled the fault code, and gave me the part number for the new part they ordered for me. First dealer had car 2 full days and "could not reproduce problem." Funny as when I picked up the car from the first dealer, immediately the nav said "please insert dvd" At that point, they didnt seem to care it was broken.

Wait... a 'dunkin donuts'? Are you sure? Depending on what store you stopped at, it could be electrical... or ..

:confused:

It is either a bad disc, dirty/defective laser head, or internal nav failure.

In older nav units, I've see this with burned copies of data discs, or as nav units age the laser optics get dirty....

Under warranty or not?

That's bullship, it's covered under the warranty.

People ask the SA "is it covered", SA says "no", their conclsuion is "not covered".

Reading the 2010 warranty statement, there is no exclusion that would exclude the DVD disc. if the disc was ABUSED- as evidenced by scratches- they could deny the claim. But that is a finding and not just a 'dvd is not covered.

Editorial comment: BMW seems to determine warranty coverage- new car and CPO warranty- based on a parts list. Unfortunately (for us and them) the terms of the warranty cover BOTH parts and 'failure modes'... so a part could be legally covered if it fails one way, and not covered another way. (Clutch is one example.)

Anyway, I bring this up so people know to not just rely on 'what the dealer says'
