TomTom Navigator 6 Randomly Starts up? - tomtom navigator software

I have a Dell Axim X51v running Windows Mobile 5 I also have TomTom Navigator 6 on an SD card, as they are to be installed. When I returned to my PDA, or drop from the standby mode, start the TomTom software at random?

Someone knows what it is and whether an update?
Thanks
