Hi, I have a Garmin 830 purchased in Australia - I'm loading a bbike map extract of San Fran.
Ive extracted the map as Garmin Openfietsmap Full and added the gmapsupp.img to the "Garmin" folder on the 830. (also tried lite)
ejected the 830 and when going to view the avalble maps
setting> Activity Profiles > Road> Navigation> Map> Map Information
the newly added map is not listed - only the "World Wide DEM Basemap" and 3 versions of AU/NZ maps.......
Any advice - I've been on gamin chat support for an hour and they cant help........
Thanks
Mike
