Ok, I'm looking for tips on using this

radio. I'm trying to transfer music over slowly via a USB drive. I've downloaded a mp3tag editor software, updated all the genres of music. I then even checked some of them by right clicking and showing the properties of the file. They'll say XYZ genre on the PC. Put them on the drive and put them in the Jeep and load them.

Half of them have the correct genre, then half have unknown or some other crap.
Any ideas on what I'm screwing up here? I'd really like to transfer my music over as I think it's a great feature. But by no way am I editing the genre (I'm not even going to mess with album title, etc etc) one by one on half of what I transfer. I'm almost wishing I went with the cheaper radio.
