Right, I have just purchased an eTrex Vista HCx.
Yesterday I downloaded Andy's OSM maps package and copied the gmapsupp.img file into the units SD card in the /garmin folder. Turned it off, turned it on and it saw the map and showed it on screen, Success.
However today I turned it on with the intention to go round the village and pick up some missing roads. No map shown!
Can anyone give me a pointer to whats going on?
Thanks
Matthew
