Just completed my installation of the HP-905 system into my new 2012 VW Jetta. The center of the grill the VW emblem and license plate are covered in Veil, the headlights are not.
Here is the location of the remote in the center console.
Here is the location of the CPU. Look carefully at bottom of fuse panel.
Here is the head on the left side. Again not easy to spot. Right side is similar.
