just got my zumo 550, steep learning curve ! i have been trying to load about 200 music tracks, both to the zumo and to a loaded sd card. looking in the folders on the computer all the tracks are there, but when i turn on the zumo there are only ever 6 tracks listed. am i doing something wrong or is the zumo busted already !!! i can't go to italy with just 6 tracks to play !!!!!
