I'm trying to get OSM data loaded onto my Garmin Nuvi 260. I downloaded data from , extracted it, and put the contents on a freshly FAT32 formatted 8GB microSD card. The contents are as follows (/Volumes/NUVI is the mountpoint on my machine, "Garmin" is in the root of the SD card):

/Volumes/NUVI/Garmin/gmapsupp.img   <--- the 3.3GB file from OSM

When I insert the card into my Nuvi 260 and power it on, I see a green progress bar on the boot screen of the Nuvi (which I don't see under normal operation, eg without the SD card). After powering on, which takes ~30 seconds, I open the maps/map info options, and unfortunately do not see the OSM data; I only see the stock "City Navigator North America NT 2009".

Any suggestions on things I might have missed along the way?

Thanks so much!

nuvi 260, Software Version 2.80

I don't own a Garmin, but maybe you need to work with a '/map/gsupmap?.img' as suggested for Nüvi 2350?

Garmin/gmapsupp.img should be ok, no other names are allowed as far as I know, btw what is this file ._gmapsupp.img doing there?

(from reading the question, the questioner has already done this bit, but for the benefit of anyone else coming here):

After installing a new map, you'll probably need to turn it on.

On the Nuvi 1300 in front of me, I have to select "tools / settings / map / info" and ensure that the box next to the map that you want to use is ticked.

Maybe your nüvi wont accept large SDHC cards (my 310 only accepts cards with max 2 Gb capacity)

I ended up using to build a map that was relevant to my area and fit within 2GB.
