I have not tried this but since I was looking into buying an N2 I started to do some research.

I found this on a VW forum someware credit goes to the original poster:

This will Void the Warranty on the N2:

This bypass will do three things:
1. Makes all nav functions available while driving.
2. Make video playback available while driving (BAD BAD Thing).
3. No parking brake warning box.


AVIC-N2 lockout bypass:

Underneath the MAIN unit (not the hideaway) is a small silver sticker, peel this back. There are two contacts with the label "R197" drop a bit of solder between these to connect them (I wonder if you can use a conductive pen instead). You must also ground the Parking Brake wire.

That is it.
