Hey guys

I tried to search but I have not come up with much.

I just upgraded to an MKIV system and everything went smooth. Here is my issue.

When viewing the map in any mode (such as perspective or 2d) the little arrow on the map sort STOP AND GOES instead of streaming along smoothly. My MKIII system looked like atari but it followed the road I'm on with no hesitation and the arrow moved along smoothly.

I upgraded to V32 last night and I'm getting the same effect. The NAV dvd is not a burn (oem bmw)

Do I maybe have a scratched/Dirty DVD? Maybe try a DVD cleaner?

All other aspects of the MKIV run very smoothly and crazy fast compared to the MKIII.
