I downloaded a map (from extract.bbBike.org) as a gmapsupp.img file. Their instructions say to copy the file to the gps device's sd card under the Garmin directory, i.e. Garmin\gmapsupp.img. I did that, but my Edge 1030 doesn't recognize it. I've successfully done the same thing with an earlier Garmin gps, so I'm guessing this mode of transfer doesn't work with the 1030. Is there some other way of installing a *.img map on the 1030?
