the programmable buttons on the wheel are limited in their usefulness. There is a limited amount of assignments you can give to each button.
Options include:
-Mute Audio
-Next Entertainment Source
-Repeat Navigation Instructions
etc, etc
you cant give it whatever assignment you want.
If you have Idrive, however, those buttons next to the DVD drive are programmable to a lot. You can assign them to phone numbers, radio stations, navigation waypoints and more!
