My nuvi 660 turns on but displays "loading maps"
Hello,
The problem is that the nuvi 660 gps receiver is jammed and needs to be reformatted.
What you have to do is to disconnect the gps, and connect it to a computer, then format it.
After formatting it, you download the self extracting archive files for your nuvi on to your hard drive, then connect your nuvi to a free USB port on your PC interface cable and allow your nuvi to initialize and enter USB mode, Unzip the files by running the downloaded executable files, then follow the instruction provided by the launched update application on your PC.
Then install it back in your car and turn it on, it will work once again.
Take care and good luck
i hope this helps?
I have the same issue (with my Nuvi 660). Did you ever get yours working again?
I am charing the Garmin with ubs and computer, but it will not load maps nor start up.
