You can try a master reset. With the unit off hold your finger on the upper right hand corner of the touch screen and tap the power button.  Continue holding your finger on the screen until you see a message "This operation will erase all waypoints, do you want to continue?" (this could take up to a minute)

Tap yes and the unit should reboot then attempt to acquire satellites.

My nuvi 660 turns on but displays "loading maps"


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?

Corrupted the software

It depends on how the files were corrupted. If the source of the corruption is not physical or magnetic damage to the memory chip where the software is stored, you should be able to reinstall the operating system software and the new maps right from your own PC.

First I would recommend going to the Nuvi 660 page in the Garmin website, look for the link to "downloads and updates", and download the most recent software update. The update is free.

Once you have done that, try reinstalling your maps. You can only load Garmin maps into your Nuvi.

If you are in the US and your memory storage is not damaged, I can update your GPS and install the map for you if you prefer.

Cant enter pin or screen is frozen

Look near the SN # and press the reset button.


with the garmin off, hold down the right bottom of the screen and turn the garmin on, it will then ask you if you want to perform a hard reset. Choose yes and that should fix your problem.

1. Enter the correct PIN.
2. Go to the secure location where you set the PIN and the unit will not ask you for the PIN.
3. Send the unit back to Garmin to be unlocked.

I have had sucess in unlocking Nuvi's but I will only do it for owners who can prove ownership through a valid sales receipt and proof of ownership through registration through Garmin.

Spell county? Never seen a county option on a GPS. Usually its zip or city, street, street number.

Mapsource update CD

Hi check out this wed site, it will help. HT maps for the Nuvi are NOT for PC use. The map load onto the GPS as you install Mapsouce. Reinstall Mapsouce and take option 3 on the startup page of the program.

Good luck

Nuvi 660 -- Loading Supplemental Maps

The best price I could find in the US for the
Euope maps was about $230 -on the internet - normal retail is $299. You have to buy and use it off the SD card, so depending on how long your trip is it might be more practical renting one, unless you want to try selling the SD card after you return.

You cannot replace American maps with European maps.  Garmin does this in order to protect the European retailers.  The European SD card eliminates the need to load the maps into the 660, however, if you need to use the card slot to store extra data such as MP3s then you might be better off buying the 670.
