i seam to keep having to reset my orientation on the map. i started out my 60 mile trip with the indicator pointin in the right direction. soon little by little, my icon rotated until i was "driving backwards" my map went from flowing top down to going sideways! why is it doing this?

are there these problems with the z3?

Is the antenna on the outside of the car? Seems like a common problem for those that try to run it on the inside.

I had to move mine from under my dash to on top of the dash to get it to work right. Every once is a blue moon it still goes crazy. But I think that's more from 5 floors of parking garage.

yes the antenna is on the outside of the car.
