Nuvi 660 -- Loading Supplemental Maps

I have a Nuvi 660 loaded with North American maps, but I am about to go on a business trip to the UK and would like to take and use it with me. What's the best method of loading UK maps? The Nuvi manual is all but useless. Can I just purchase the maps on an SD Card, slide it into the slot and it will work? Please advise.

Re: 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.

Why when I try to enter an Address with State = California, my Garmin Nuvi 660 only shows "Cayman Brac" and "Connecticut"? I'm on software version 4.90 and I have "CN North America NT 2015.40 ([1] Lower...

CN North America NT 2015.40 ([1] Lower 49 States NE)
NE = NORTH EAST... California is not in the North East of the United states. This device only has a small internal memory so you need to use a 4 GB memory card and load maps to that card with MapInstall:

My gps is set on peru and i am in the us, the gps can not find the maps of us. thx ziv

You'll have to load the North American maps into the unit. Go to and register your unit with the site. You will then be able to purchase the north american maps and download to your unit using the Garmin updater on the site. The maps are all serialized to work with each unit ID, so a North American map on another user's Garmin will not work on yours (it is Garmin's proprietary copy protection system).

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?

Garmin Nuvi 660 lost Europe maps

Eventually managed to speak to a man at Garmin who confirmed that it was not loading any European maps because it didn't have enough spare memory to load them all. He said that he would email me instructions for freeing up sufficient memory, the email never arrived but I decided to delet all the voice languages that were no use to me and all the other language 'help' files and tried again - it worked.
At no point did I get a 'insufficiant memory' warning, which would have been very helpful, nor is there any guidance for how much memory will be required when embarking on the update. Take note Garmin...

2009 map update not loading

Fixed. Called Garmin. It seems that version 4.90 FW on the Nuvi 350 (which came shipped on my 350) has a bug where it cannot communicate with the Garmin software either to update maps or update FW. Tech from Garmin e-mailed me a patch that I copied into the Garmin folder on the Nuvi itself, via USB and Windows Explorer. I then rebooted it; the patch installed itself which then allowed the unit to communicate with the map upgrade software and all is well. 2009 map update is now installed and the Nuvi is working fine again. Haven't tried upgrading to newer FW yet; will probably leave well enough alone.

Loading maps updates

Most map providers will advertise that their maps are Garmin compatible - just make sure your provider confirms this.

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.

Map fro Garmin

As far as I know you can only buy maps from Garmin, or a Garmin retailer.  The 660 should have all the maps for North America already loaded in it.

You can purchase Points of Interest (POI) databases from a variety of sources.  Just google POI.  These are not maps but they are adresses for points of interest such as restaurants, special services, and even speed trap cameras.
