Although it’s been a while in coming,have updated their free UK OpenStreetmap based Garmin IMG files for use on Garmin GPS units. Although they are still having some trouble with producing the canal map and cycle map versions, they have released an updated (July 2010) main map of the UK for general use (or for use in adding vital extra detail when you are out geocaching). Importantly, with this release, they’ve also created a version with routing information (although that does make for a large download). I’ve been running files on my Garmin GPS for some while (since they started), and am grateful for the detail it gives; it seems a lot of the early footpaths were actually added by geocachers, so whilst last year you would often find the obvious footpath to a geocache on the map (and often stopping at the cache, as they turned round and went back the same way), this year a lot more footpaths (and roads in general) have been added; it’s still not complete ( that is, the source of ‘s data), but it’s a lot better than it was.
If you are interested in loading up UKfiles onto your Garmin then head over to to download the files, especially if you haven’t yet gone on holiday this year, and want to improve your GPS maps.
