hi - i have a tough question ;-) - my Topo Germany 2012 Pro works fine in Basecamp and MapSource and - in principle -on my 62St -i just discovered on aMTB tour today that one tile will not display in the 62St -we got lost since nothing than the actual track was displayed ... -all the other tiles around this single one are visible in 62St,though ... -in MapSource and Basecamp this invsible title is displayed fine - reloading the IMG to SD did not fix the problem,loading the map to 62St via MapInstaller did also not fix the problem ... - any clue what is wrong here or what i can do ? btw - when using Topo Germany V3 on 62St the tile is displayed fine ! thxs a lot in advance !
