I'm thinking about getting my girlfriend a headunit for christmas. She's got a very base level 05 Cobalt and the headunit is a joke, but I know nothing about car audio. I read the sticky, and of the three $100-$200, the Panasonic CQ-C8300U looks the best. She got a Dell DJ mp3 player as a bonus for the apartment/dorm she's living in, and I want her to be able to plug that in. What will I need to do to get the DJ to work? Is $200 a good price for this unit? It's got more features than I was planning to get, is there another in the $100-$200 that is a better deal? Thanks for your time.
