Is it still possible to load OpenStreetMaps OpenStreetMap maps on to the latest Garmin etrex 20? I was told in my local store at the point of sale that Garmins now block this function. I decided against purchasing until I checked this out but cant find any information about devices 'blocking' non Garmin specific file formats online. Hopefully the salesperson is wrong, as I was really looking forward to getting started with a GPS. Can anybody advise?
