Yes, the stock HU for your year is the II+
The correct Connects2 interface should have the integrated 40 pin connector (check their website)

should add:
Metra VW53 (or VW54) - Antenna adapter
Scorche or Metra Dash kit

You would also need the Kenwood specific lead

Hook up that brown wire to the Blue/yellow remote control wire off the Kenwood unit.

If your car is Symphony II+ (chrome trim around knobs) or RNS-E then you use CTSAD002 and EU55 Antenna adapter.
