Question about Garmin Nuvi 660 GPS Receiver
Not sure what happen but I accidently pushed the monitor and then I never heard any more sound. I tried the volume and still no results
In case it is a software problem try this and see if it will fix it......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 try recover from the problem.
