Navigation ISSUE (2006 E320 CDI)
The navigation will work perfectly sonetimes, but not all the time! It works perfectly when I first start the car, usually in the mornings. After I cut off the car (to shop/get diesel) , the pointer on the map will not move (and is frozen) even though I have up to 10 satellites showing with the coordinates changing constantly (while it is frozen)! When I enter a new address, it will usually say "off road" even though I am on a major interstate! Other times, it will "appear" to take the new entry for navigation, but it is frozen on the last street entered (when it was working).and will not update!
I have tried 3 known good changers, new GPS antennas, and 3 navigation disks with no joy!
Again, the navigstion works perfectly when I first start the car, usually in the mornings, or let it "sit" for several hours! I am thinking there is another problem besides the changer, antenna and the navigation disks!
Any help EXTREMELY appreciated!

Even though on one responded to my thread, I found the problem (frozen navigation screen)! Ironically, it was the "Central Gateway Module" below the steering wheel (attached to the drop down panel)! I cannot explain why the CGM had anything to do with the navigation! This afternoon, the navigation was frozen again! After replacing the CGM, the navigation began to work perfectly! Also interesting, I had no oil amount on the instrument cluster until the CGM was replaced. It is now working as well.
Hope this will help someone with this ODD problem I was having!
