VW Car Net
I'm not a huge fan of OnStar or similar systems. "Big Brother is watching," right? The Jetta w/Premium comes with VW Car Net, VW's own telematics system. I hope to never need most of its features. But the remote monitoring will come in handy. Since I'm not the primary driver of the car, it's nice to be able to pull up the odometer, fuel level, and time to next required maintenance from my Android device.
