My tomtom Go 730 screen kept changing on its own, just as if I was pressing the arrow button on the right hand side of the screen. A curious behavior - spontaneous "clicking" on the touchscreen. Touchscreen seems to be OK, everything works - but this effect is frustrating.
I have actually formatted the tomtom and connected it to tomotm home and it reinstalled the software. But this didnt help either. Does anyone here have any ideas as to what to try next ?
