Good to know. Ya, the shuffle was freshly charged. From what I understand, the player needs to have the 'multi-pin' type connection, NOT the "male" type plug. I may just go ahead and get a nano. Tis the season to hopefully get a respectable deal on one. It's something that I want to just be dedicated to the truck, so I don't want/need anything too big like an iTouch. The nanos are pretty small and should just hide in the console where the ports are.
Again, thanks so much. You really helped me out!!
