yes you can.... make directory named [SD-Card]:\Garmin and put GMAPSUPP.IMG in it

If you use Unlocked image not need more

If you use Locked image make file GMAPSUPP.UNL also... generate key with JetMouse

i have an unlocked Gmapprom map image for CN2012 europe where can i get a gmapsupp image from ?

also attached is a picture of the contents of the garmin folder on the device itself what do i need to delete from here to remove the old map

just rename....
you can also replace old one in internal memory if you want
old map is gmapprom.img remove also gmapprom.sum

removed the gmapprom.img and gmapprom.sum from the device the dreated a folder on the SD card called Garmin, in this i put GMAPSUPP.img file in that folder but the device is not seeing the map. im using a samsung 4 gig SDHC card

A Garmin Nuvi 660FM can't handle and therefore not read SDHC cards ... 2gb cards are the maximum you can find that's not SDHC.

is there a smaller europe map then that could go on the device

I usually compile a new gmapsupp.img from Mapsource, just choosing those countries that I most likely will visit ... It's a long time now since a whole Garmin Europe map fitted in my 660FM at the same time.

Western Europe + Eastern Europe = FULL Europe ;-)

eg. put Western europe map to internal gmapprom.img and Eastern europe to sd gmapsupp.img

western europe on its own would do is there an unlocked image of that any where?

yes you can...

eg.
internal:
spain & purtugal GMAPPROM.IMG
uk & roi GMAPSUPP.IMG
some devices support also GMAPPROM1.IMG and GMAPSUP2.IMG


sd:
france GMAPSUPP.IMG

just make testing...test with one image all names what works you can use one map same time also....
