Success!!
Even though many dealers told me it was not possible, I have successfully installed the MMI High equipment and the touchpad and navigation work great!
I did the installation myself. Total out of pocket equipment cost was $1,000 US.
Some tips so that I can give back to the community:
1) Make sure you purchase correct head unit. I originally purchased European head unit. Once I got NAR version, all was great.
2) No VCDS coding required.
3) No new wiring hardness required. Only the LCD connection will need to be shaved in order to fit.
4) Component protection must be removed by dealer.
5) Separate GPS antenna is required. You can potentially use an OEM triple integrated tuner (Antenna, Sirius, GPS), but I found it so easy to use a generic GPS antenna.
