I have a Nuvi 660 and it is great, I love it.
Recently during a webupdate, I lost my map data and can not get it back, I
am working with Garmin Tach support to get the final solution, will keep you
informed.
During my troubles, I was wondering how to determine if my map data was
corrupt or missing.
I eventually had to call Tech support and I figured I would share the info
in case anyone else may want to try this procedure, it gives you the option
to run diagnostics, so if there is a major problem you may be able to give
Tech support the trouble code or error report if there is one.
It is very easy to do and it does not erase any user info unless you confirm
at least twice.
Step 1> Turn your Nuvi unit off, remove any SD cards from the SD card slot
and make sure that the unit is not plugged into any computer.
Step 2> Place a fingertip on the upper left hand corner of the touch screen
and keep it there while turning the unit on, a prompt should read " Do you
really want to start in maintenance mode?"
Step 3> Select the yes button
Step 4> Enter your PIN if enabled
Step 5> Main Maintenance Mode screen should have 4 selections :
System information
View Diagnostics
Clear User data
Clear Waypoints
Step 6> After some selections the unit should reboot and you check to verify
unit after rebooting
