big bucks 10 years ago and even bigger bucks today on the unit in the trunk.
my son picked up a am/fm/single cd/ipod input/hands free to your phone and a usb in front to play music for around $150.00 bucks.
crap- nice looking unit too.

most of my music is on my phone linked to my vans hands free- but you can put a lot of music on a usb stick!!!!!!!!!!!
