For first time (ever) I cannot get the USB (or the AUX) option to show when I press source. I have a lot of music on the USB, and it works fine on my laptop.
Help? 2010 S Cab.has been bulletproof...so far.
Oh- it does not allow me to see Miles, only km...last year or so.

 

do you have a cd in cd-slot? You'll need one to show Aux source. Maybe for USB as well.

 

2009 C2S 180K miles

Are they activated in the SET menu? You can hide them with this setting.

If you can see your USB stick, but no files, that is a different issue. Post here and I can help on that.

I put a CD in the slot and it allowed me to select the source, which I did. And it worked. Not clear why this happened but I know how to fix it now.
Thanks.

 

I had this happen when I installed my sat radio board. Speedracerf4i is spot on with his solution.
