I'm shopping for a car, and I found a used 2002 Passat GLX 4Motion V6. While there is much to like about the Passat, there are some features that I strongly dislike and I'm wondering if there are fixes for these. (I googled and didn't find any decent VW forums. If they exist, please point them out to me.) First, during my test drive, the steering wheel radio tuner buttons made the radio scan to each next available station, rather than cycle through only the presets. That odd design choice is enough to keep me from buying the car. Can it be set to cycle through just the presents? Another radio question: can the in-dash radio be upgraded or changed out for one with a single CD player? Having to open the trunk, then open the access panel, then eject the CD cartridge to access the CDs is just no good for me. And a whole new stereo would be nice; I find the '02 stereo controls to be a real mess especially compared to the clean design of the Accord and Mazda6. (They've cleaned this up in the '04 Passat, but that's out of my price range.) Finally, are there any aftermarket mods to increase the performance of the car? (I googled this and couldn't find solid information). If so, do they void the manufacturer's warranty? The 4Motion Passat is a bit sluggish compared to competitors such as the Camry, Accord, Mazda6, and Altima. A used '02 Passat is very appealing, but the poor stereo/CD design kills it for me. Thanks for your help and insights.
