Thread: gps62s startup issue, master reset won't work, any experts out there?

Yeah I had a go with mapsource as others said the same, but by that time I'd become reasonably familiar with basecamp. From memory my frustration was mainly trying to transfer birdseye imagery between devices, when one might have an expired subscription. In the end figured out it is easier to use Google earth to make custom maps, probably took me about 40 hours though.
