    Unfortunately this won't be of help to you, anyone from the UK viewing this question can obtain free maps here: talkytoaster.info/ukmaps.htm Commented Feb 21, 2014 at 14:14
  • I can strongly recommend OpenFietsMap and OpenMTBMap which are based on OpenStreetmap but heavily optimized for cycling. Map data contains information such as kind of track, ground, slope etc. and supports active routing (turn by turn directions). You can find detailed information on exporting of maps and how to transfer to Edge in tutorials section of OpenMTBMap website. Give it a try!

You can get map files that work on Garmin devices (I haven't tried with Edge) from this site. You can select predefined areas (countries, provinces) of the world you want, or create custom selections of just your area. They generate a map of your desired area and send you an email when its ready so you can download it.

  • Had anyone tried with this and verified that the map and turn by turn navigation actuall work with this map set?

  • Haven't tried yet (maybe I will tonight if I have time), but the first set of radio buttons gives different options, one of which is "Routable Bicycle", which sounds quite promising.

  • Do these maps have POI?

    Also worth saying that you can download several of these maps, and as long as you give the maps unique names on the micro SD, there's no problem with the device reading them (true for the Edge 800 at least). The map doesn't have to be called gmapsupp.img, you can have france.img, italy.img etc. if you wish

    I have used these maps on an edge 810 without any problems.
