iTunes to MyGig

[Katrina2475]

Is there a way where I can use my thumb drive to get some songs off of iTunes to the MyGig stereo system in my car? From what I've read I can do it by burning to a CD but I'm trying to avoid running to the store for CDs if I don't have to. The majority of my songs were purchased from Amazon and those are easy but I have a handful on iTunes that I want to transfer over.
