@bommelb - thxs a lot for your suggestions, i will check - in the meanwhile i deleted the recreational map europe from my 62st (i don't need it anyhow) and loaded the Topo Deu 2012 into the 62st main memory - guess what - the tile shows up ;-) - i think that will work now AND it gives me free space on the 8GB SD card (yes, the 62st works with 8GB !) to put the rest of europe TOPO maps on it - happy now ^-^
