go 520 screen keeps changing

HELP!!!, hi, the screen keeps changing from the inputed navigation route to different screens ie walk there, route selection ect, the voice is still telling me where to go for the original destination but there is no live screen map, it comes back if i keep pressing back and then navigate there, but then goes barmy again, i have done several resets and a restore but no difference, please help
regards

Insert a thin piece of card between the screen and the bezel, run this around the whole edge of the screen to dig out any dirt lodged in the gap, once you have done this a few times the device should behave properly. It is possible to remove the screen surround panel but its quite difficult so I would try the thin card trick first before you start looking at stripping down the device - Mike

thanks, i will try that, as it still has about 3 weeks g/tee left i dont want to strip it down, i bought it from total pda, is this fault covered by g/tee
cheers

Just try the thin card trick to dig out the debri and the device will be fine, stripping the screen surround off the device is quite an involved process and shouldn't be needed in 99% of cases as the card will dig the dirt out making the screen work correctly - Mike
