How do I prepare an SD card with maps of france to work when I plug the map into my nuvi 360. can i be sure that the present US maps will not be hidden when i do this? Many thanks, Bob

I think the section What if I have an existing gmapsupp.img file should help you. However, I am not sure I understand your setup. Where is the US map currently? Why do you fear that it will be "hidden"? If you delete a new map on your sdcard it should be as before.

file names: use only short filenames (e.g. france.img) with 8 digits and 3 ext.-digits. on your navi go to menue, settings, map, map info and activite osm-map

Many thanks, gwo4902. That seemed to do it I may have had two img extensions as well. Thanks again to all who helped.

I am pleased you have got the map up and running, I hadn't encountered the name length problem or seen it mentioned here before.

I think the 360 can only recognize gmapsupp.img so try to rename it back. Another issue can be that this nuvi cannot read SDHC cards, so you can use only cards up to 2gb.

gmapprom.img or gmapprom1.img are also alternative mapnames that can be used on some older nuvis.

The wiki states that the Nüvi 3**-series can handle multiple gmapsupp-files with different names. So make a folder with the name 'Garmin' on your sd-card, copy the gmapsupp.img to that folder and voilà! If there is already a gmapsupp.img, first rename the new file to for example france_gmapsupp.img. After starting up the device, it will read the new map. Then it is possible to change the map-settings of the Nüvi so the new map is being displayed.
