Thank you, thank you, thank you. Somehow something went horribly wrong with my F500BT. This thread, many days of trial and error, and a backup I found online are the reason I am up and running again.
Only problem is that the backup I downloaded isn't in English. I'm going to try to combine my backup, that was somehow corrupted, with the downloaded one to see if I can get it back to English! lol
At least it works again. Having no music in your car really sucks!
