Bought a Jetta in 2000. Best car I've ever owned. Didn't like the stereo though. Tried to replace it with an aftermarket system and was told that doing so would void the warranty on the door locks, the car alarm, everything wired into that cabling system. I lived with it for ten years til I sold the car, but it's one of the first things I ask about when researching a new car purchase.

It's one thing to make the center console non-standard, it's another to prevent the installation through warranty restrictions.
