I've tried NUMEROUS MP3 players as well as NUMEROUS USB sticks and all have given me this same error REPEATEDLY (formatted FAT32):

1) USB function selects perfectly fine
2) I can select artist/album I want to hear
3) Music plays just fine for a variable time - 2 min to a few hrs
4) Music hangs and track select function frozen
5) When I select a different music source - it takes at least 15 sec to switch to that other source (satellite radio or FM, doesn't matter)
6) I can re-initialize USB at this point but usually once a fault occurs in that driving session a second USB fault occurs quickly

I had the dealer techie run a diagnostic - but no fault codes came up. He said he didn't know of and couldn't find any tech bulletins on the issue.

Please help with any info if you've had this fault. Thanks, Rick

what size is ur USB ??? maybe format it to a FAT

 

I've had the occasional hiccup similar to what you describe, but no ongoing problems.

 

Mine has been flawless. I am running a 16gb HP usb drive.
