The Skoda kit retrofit into your Mk6 might still be on the table for you...from what I read, it allows full MFD integration with phonebook access.
Do you have the P/N for the Skoda kit?
1K8 035 730C - aka 9W2. is the version installed in my car. This is a basic kit and and only answer or end calls, mutes and adjusts volume. A menu does not show in the radio or MFD. It also cannot initiate a call.
I read 5N0 035 730 or 1Z0 035 729 can be updated to replace 9W2. Someone on vwvortex has upgraded to basic kit to 1Z0 035 729 (9W3?) and now has full phonebook with mfd support with voice dialing. He indicated that he will post a writeup of the swap this weekend.
I guess the North American Golfs get the basic 9W2 kit because VW does not want drivers to initate calls while driving, but important calls can be answered while keeping both hands on the wheel.
