OpenStreetMap for Garmin Edge

The standard OpenStreetMap downloads for Garmin may be appropriate for car drivers but the end result is little use for cycling using a Garmin Edge 605. I'd like to use the cycling specific data on OSM (see OpenCycleMap for the UK, or OpenFietsKaart for the Benelux) data instead with Garmin's Basecamp for OSX.

Do-it-yourself
As there doesn't seem to be a pre-made version anywhere, I had to role my own using these instructions. That got me a gmapsub.img, which worked on the Edge 605 albeit with very slow rendering due to an excessive level of detail.


These instructions are needed for converting to the Mac gmapi format used by RoadTrip and BaseCamp.
