I plugged my new nuvi 65 LM into the USB port of my MacBookPro, copied gmapsupp.img to the Garmin folder. Then ejected and disconnected from the computer. When I go to My Maps to select the map only the original map is there. There is no OSM map. The file is only 17MB so there is 2.7 MB space remaining so there plenty of space.

Please can somebody help?

where did you download the file? Try from another provider, e.g. . And if possible I would suggest to use a microSD card - that's usually faster (for bigger files) and you can easily store several maps on it.

are you sure that it's called exactly gmapsupp.img, without capital letters ?

auguslind thanks. I was had an opentopomap on a memory card used in an old Nuvi 1310t it didn't show as a choice in tools: settings:map:info tic map of choice, until i renamed it as gmapsupp. It confused me as it worked when the Nuvi was connected to Basecamp or tested in an Oregon 450 and my Etrex 30. I had forgotten some Garmins only work with a map called gmapsupp. Thanks again.

Try checking the spelling and maybe a alternative device ( if you have one) or try it with Garmin Basecamp.

I thought it was only the oldest nuvis that require the file to be called gmapsupp.img. I have a 200W which has this limitation. It will accept a file called gmapsupp.img (all lower-case) in the Map folder of a SD card. However my 1310 - now also quite old - will accept multiple maps with filenames ending .img (lower-case) in the Map folder of an SD card. I never install maps directly on the devices.

If using an SD card I would suggest formatting it as FAT32 if it still doesn't see the file, although the nuvis are nowhere near as fussy as some cameras when it comes to SD cards.
