Have you unlocked the "gmap3d.img" map?
Do you have a compatible unit?
Is the "gmap3d.img" file in the correct path for the unit?
Read post #1 and the section where the MapID is mentioned.
Also here - [Only registered and activated users can see links. ]
Not sure if both trafficTrend files would be needed. Keep a backup of the previous one if problems occur.
