Hi all, after a dozen times trying to get this SD card problem sorted and with still no reply from Garmin or Navigon, i went back to the manual to see if i could fathom it out, now i dont know if this is a true fix or not but it is what i tried, i noticed in the manual that the operating system on my maps and more is Microsoft windows CE edition, so i decided to use an online convertion website to convert all my mp3 files to WMA (windows media audio).
after i converted all my mp3 files to wma i then plugged my maps and more unit into my laptop and replaced the mp3 files on the 2gb sd card with the wma files, TA DAH ! it worked for the first time since my maps and more came out its little box and it is working the way it should, its playing all my wma music files it allows me to select folders and skip forward to my chosen music file no problems. i hope this has fixed this problem for good if not well its back in its little box and back to the volkswagen dealer fingers crossed time will tell.
