CA-WestProvTopo Map img file copied from computer to micro sd card in gpsmap64sx. GPSr does not see it. Basecamp does not see it. File explorer sees it when hooked up to GPSr. Is this img file not compatable with garmin? Thanks
IMG file have a bit set that determines whether Basecamp can 'see' the map.[This is to prevent maps created thru Basecamp being seen double]. There is a tool called Javawa Device Manager that will change the visibility - worth trying.
Thanks jolly47roger. Javawa got me going :)
