Guide :GPS : RoadMate 700 GPS Receiver
MRM 700 won't start; screen flashes white . . . help.
I have a Magellan Roadmate 700 that has stopped working. After a long struggle with it shutting off at every bump in the road (a new cradle solved this problem), I now am facing a new problem with this otherwise great device.
Recently the device's screen started flashing white when I push the power button, and continues flashing and unresponsive to all button input. I must disconnect the power to stop the flashing. In addition to the flashing white screen, the 'View' button is lit orange and occasionally there is a single vertical black line on the flashing white screen.
