I recently bought a 2002 745I and the navigation screen keeps showing my location as if I was in Ohio. I guess this would be ok except that I am currently in Virginia. The car has the CD based navigation system with the split screen and came with the # 5 CD map(Midwest & Ohio Valley, 2001.2 ). I have come to reallize that this navigation system takes several different CD map disks each specific to the different regions where you are traveling. With this in mind I purchased the full 2008.1 CD disk map set. The dealer assured me this set would work with my car's navigation and that it would have the most up to date maps currently avalible for this system. Unfortunately, after I put the new # 6disk in (New England & Mid Atlantic), nothing really happened or changed. After poking around for a bit, I was finally able to find my house street under one of the choices (I think it was "location") and find things in the POI section (local gas stations and stuff), however when it goes back to the main screen that shows the arrow in the circle, it is still showing me in Ohio near lake Erie. The arrow & map are moving but it is not following any roads(just cutting across grassy areas etc...). Is there a simple fix to this issue without taking it to the dealer?
