MK4 reads Navigation CD but not DVD?
Sorry, this is a first post. I've searched through the archives here to no avail, so here it goes:
On my '01 M5, I swapped out the MK3 for a Ebay MK4 unit from Lithuania. I've updated the firmware from v23 to v26 to v27 and back to v26. I've pulled fuses 56 & 58 to no avail. No matter what I do, the MK4 unit refuses to read the Navteq DVD. I have tried originals and copies, but they're all the same : "Cannot read CD/DVD".
Funny thing is that the CD's are reading fine. I kept the navigation CD from my MK3 unit, and it works perfectly in the MK4. It's only when I pop in a DVD that it fails.
Has anyone else had the same problem?
Thanks,
-joe
