I have a problem. I try to unlock with the unloker from the first post but it did not work. I unlock the map with keygene 1.5 (25 caracters) and i use mapsource 6.15.11 pached and it see the map unloked. I send the map on garmin mobile xt (on 5800) it create a map on card (gmapsupp.img) but when i open the gps it did not see the map. It see just one map (gmapsup2 -Romania-). I change the titles between the maps but still the same result: did not see Garmin City Navigator Europe.
