On my 09 Rex, it likes to rearrange my playlists into alphabetical order by artist then song. Sometimes it is just random. Just so you know how I do it.
-Plug iPod in
-Hit category, 2, then use the arrows to select the playlist
-No other options changed
When I plug into my computer everything is the way I left it. Am I doing something wrong with the head unit or is it just the way it is?
