Question about Garmin Nuvi 660 GPS Receiver
When I switch my 670 on it finds the satellites and works fine once I begin to move it switches to Acquiring satellites and the ? symbol appears. If I switch to the satellite indicator it shown no connection. If I then switch it off and on again it occasionally works OK for another 2 - 10 minutes. I have tried a re boot but it has no effect.
Try this and see if it fixes your problem....first disable bluetooth then follow these steps.
1. Power off the unit.
2. HOLD down the power button and you will see "Pre Boot Mode" appear on the lower part of the display. KEEP HOLDING the power button down and the display will flicker, do this until the pre boot mode message disappears. This seems to take a long time (60 seconds at least).
3. Once the pre boot mode message disappears release the power button and your device will perform some activites to recover from the above problem.
