Reset button behind the Antenna, press this in for a few seconds.
Use the Web-updater at Garmin, to update it too,
connecyt it to a PC and run the update,
If still playing up, Use the Firmware update at Garmin for it,
(( google Garmin 660 software updates ))
Should be fixed then
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.

Can you update the firmware on your unit
my k800i sony phone had a problem synchronising and would freeze, then one day the nuvi 660 updated the firmware by itself and has been fine since, only problem being the volume, a bit low when trying to contest with large diesel engine, onboard speaker keen to distort over 80% volume
yes you can but you have to disconnect your device from the computer.
Turn on GPS for few seconds and turn off . Back to your computer connect the usb m, go to GARMIN FILES , MP3S and delete the songs. You should be able , i just did it.
No problem reported , i had 2 NUVI 660 in front of me. Did you flip the antenna parallel to earth surface. Wait 45-56 seconds and you should get a signal.
If your are on vertical position with you GPS . Place the antenna at 90 degres so she will be paralell to earth.
You should get a signal very quickly. No other report this problem.
Make sure you had also the last update via the web updater
No not the issue. Didn't happen with my STREET PILOT C340
