Question about Garmin Nuvi 660 GPS Receiver
Will not turn off, stuck on with display saying 'pre boot mode'. Does nothing but this - please help!
"Will not turn off, stuck on with display saying 'pre boot mode'. Does nothing but this - please help!"
This indicates that the on/off switch is shorted out. You can duplicate this problem by taking a working Nuvi and keep holding down the on/off button when turning it on. It will stay in this mode until you let off on the power on/off button.
