Arrrrrggghhhh - This map has now become a challenge. Nothing I have tried yields a working copy on my GPSMAPP 62s.

Tried: Jetmouse Keygen (checksum fixed) using map ID 2043 & unit ID to generate gmapsupp.unl (many times) with same result "cannot unlock map"
Tried: fast IMG unlocker and it gets to 69 and stops like previous posters experience
Tried: GarminUnlocker - no joy
Tried: Unlocking map for mapsource (successful - whoopee) but then still the same "cannot unlock map" error after transfer to device

As soon as I can find a PC with >3GB RAM I'll try the "Fast IMG Unlocker v.1.3 update 5-10-2010"

If anyone has had any success with GPSMAP 62s and this map I sure would like to hear about it

Cheers, Sim
