Power off your Garmin 660 unit. Press on continuously the upper top left corner of screen and then power on the unit by pressing once on the Power button. You should be prompted to clear all user data, or asked if do you really want to start up in maintenance mode. Press "Yes" to reset (warning: all data will be erased and lost, so backup before proceeding) or enter maintenance mode.
To back up your Garmin.

  • From the garmin drive, copy '/Garmin/GPX/current.gpx' to a backup location on your computer.
  • After the hard reset, copy your backed up 'current.gpx' from your computer back to the '/Garmin/GPX/' folder on the Garmin, but be sure to rename it 'temp.gpx'.
  • On the next power cycle, the Favorites will be read from 'temp.gpx' into the non-user accessible memory area on the Garmin where they are actually stored

  • This should reset your Garmin then I would suggest updating your device at the Garmin site. I will attach a link.

      You can also try powering off the unit a hitting the reset button under the antenna, or try the information above but pressing firmly the lower right side of the screen.

    Disassembly nuvi

    The clips are part of the connector and can not be purchased separately, however it is possible to remove a clip from another connector and install it on the connector with the missing clip. It takes a steady hand and there is a trick to get it on. We've done it many times in our repairs for our customers.

    My Nuvi 650 screen reads "The following map data is more than a year oldand should be updated. When I touch the "OK" on the screen, nothing happens, it seems the screen has become unresponsive.

    I would suggest some caution here. I have noticed a trend in anything that can be updated by the consumer---they just blindly do it and I have also seen as the result of this dozens of units crash and burn---if you have not issues and the unit functions why risk losing it?

    Turn this unit off and see later if turned on it functions or not, failing that the only way out of the mess would be a call to the maker.

    Don't just blindly say ok, kind of like getting a email with a virus and saying OK.

    My garmin nuvi 670 touch screen is not calibrated

    Have you tried using the screen calibration command? Press the Wrench symbol, then the Display symbol and then Calibrate screen. Press the dots as it tells you to and you should now have a calibrated touchscreen.
