when i added the new update i didn't remove the old updater from my card and it would not save the tracks what i did was take the card and remove the old up date and the i restored factory defaults before inserting the card with the new up date
also this time after i installed the new update i took the card out and cleared the update off it that way it will not tell you that it has the latest update on the screen when you power up works great after i did this
