I have a TomTom go 720 sat nav device. every couple of months when it is turned on a screen appears , following 30 seconds a red cross appears and starts to flash. The sat nav usually takes about a 10 day period to re correct its self. Can any one offer me an "IDIOTS" step by step guide in getting this thing to cooperate I would be very grateful.
