Hey all. I just bought my 2012 IS250 this week. I have the non-ML, nav unit. In my previous vehicle, I used a USB drive with about 3000 songs on it, and it worked perfectly. I plugged it in to my Lexus, and it sounds choppy like it is in fast forward on a CD. I have re-formatted the drive to ensure that it is a Fat32 format. My hierarchy is no more than 3 folders deep (artist/album/song.mp3). I am using a 32GB USB 3.0 Sandisk drive. Does anybody have any suggestions for fixing this?
