In my JCV directory I have 2 files: D1279020A.JCV & D1279020A.sum Should I just add here the appropriate files for Europe? Without rename etc.?
Again: what volume should be the img file CNEU 2010.30?
Also: I'm planning to buy Oregon 400t topo world preinstalled. How they managed to do it with 1Gb internal memory if just topo France is almost 3 Gb?
