I downloaded an OSM to our PC - unzipped it, then 'sent to' our Garmin Nuvi 2455LMT. The new map is listed in it's Internal Storage as 'osm generic_gmapsupp', but when I try to access the map, it is not listed in 'myMap' to be able to select it. Can someone PLEASE help, I have spent two days trying to work out what I have done wrong - I'm sure that it is a very simple mistake that I have made, but, not being particularly GPS savvy, I am going around in circles.

According to our Garmin Nüvi wiki page the file must be located in a folder named Map (see the notes for the Nüvi 2350). Try to create such a folder and move your map to it. Additionally, the name of the file must be in the form of gsupmapx.img (where x is anything, including nothing).

Hi janmatti, Is the map / data readable on the pc if yes, it looks like its more a Garmin Nuvi problem and should be posted at a Garmin help site. Look here http://www.garmin.com/uk/support/#/{f0a89a90-030a-11dc-e9ab-000000000000}/Automotive and make a selection or post your question there, greetz and happy trail.

hi please try to read similar questions by typing download osm map for nuvi in the blank line above and try Scai s solution first.

@janmatti you can't open the img file directly. You need a special application like MapSource or BaseCamp and as far as I know a converter, but I have never done this.

You could see if Garmin Basecamp will display the map when the Nuvi is connected to your PC if that works it would then suggest the problem is with the nuvi not the map.
