I have one question about my express. I have an express with uconnect and Sirius radio but I just noticed I don't have the buttons behind the wheel to adjust the volume and station. What's up with that?
I recently added the radio control buttons to my 2011 ST.
The mod was simple and if you already have the EVIC it may be as simple as adding the buttons and activating the RDZ sales code.
For mine I had to do some wiring to communicate with the EVIC and to power the EVIC control buttons.
