I've been using a Garmin V (Dave Hall's old 'un) for a while now, but the battery hatch finally gave up the ghost. So I sent the unit back to Garmin with a cheque, and got a nice new 'un back.
Problem is, it won't upload any of my Mapsource maps, saying that they're not unlocked to this unit.
Now, given that those nice Garmin people sent me a new unit, I imagine that means I'm in for a world of hurt and pain trying to get new unlock codes of 'em. But even if I do, I have no idea how to upload them to my new V.
Any ideas anyone?! Apologies for being an utter GPS numpty.
