I have the Tom Tom 730, and a 2G SD card. I have used Tom Tom Home to load about 400 songs on the SD card. I then disconnect the unit. When on the unit I go to listen to the music, it begins to load the SD music, gets to about 10% complete, and then jumps to 100% complete. It is only showing 44 of the 400 songs on the SD card. Has anyone experienced this and found a fix?
