I am about to get a deal on a 96 Mustang Cobra, and I already know that I will be replacing the head unit. I have a 30 gig iPod, so I would like it to have the USB, and also the AUX in. I have a Kenwood KDC-MP435U in my current vehicle. I thought about getting the updated model, I think it is the 438. However, when hooked up with USB it only randomly plays the songs on my iPod, I cannot select playlists, genres, etc. If that was a possibility, I may not need the aux in. Any suggestions for under $200? Thanks.
