Hi, I am a newby to the world of GPS and am running TomTom navigator 5 on a Dell Axim 30 624 BT/Wifi with a Holux GPR 236 BT receiver.

Can anybody give me a clue as to what may be causing the following problem.

Whilst on a journey following a navigation, the map image on the screen occaisionally jumps around showing varying degrees of zoom and direction. The distance to the next manouvre indicator momentarily goes to zero and then in an instant all is back to normal. This did not seem to happen when I was using the Navteq software. I just wondered if anyone has any idea as to what casues it.

Thanks, Mike
