Sorry for my stupidness, but this sounds like Chinese to me. I tought Topo France V2 doesn't work with IMG files or am i wrong? Everything works in Mapsource but if i want to transfer the maps to my new GPS Map 60Csx i get a message that the maps are not unlocked. I am not a PC spe******t neither so can you give me a solution that is understandable for not so smart people?
