navigation issues

The integration of the navigation software with the rest of the car features is great but the navigation itself has some problems I'd like to report. A quick web search doesn't turn up any place for me to report the problems directly to VW, so I'll report them in public here instead!

I live in a small US city. The other day when I asked the software to take me to Target, it insisted on navigating to the back of the building. Today, I asked it to take me to a local restaurant and it encouraged me to make a U-turn at a major intersection (which is illegal in my state).

Does anyone know where I can constructively provide feedback about the navigation software?
