My 2012 GL won't play music from what I downloaded from a SD card to a flashdrive. I got the flashdrive from Wal-Mart, actually two, both don't work in the top case plug. Works fine in my car. It has been discussed here before and someone said you need a faster flashdrive. I went to RadioShack and the kid looked at me funny said he didn't know what I needed. Anyone not out riding that could help with info?
