Im looking at the Virtual Reality Sound VR3 CD Player w/ USB and Scan Disk Inputs to get for my truck off of walmart.com
http://www.walmart.com/catalog/product.do?product_id=4744710
I have two questions:
1) Does it mean I can transfer music files from my iTunes onto a flashdrive then play them on the radio?
AND

2) What is the purpose of #3 on the enlarged photo/the stereo audio cable for?
THANKS!
