To all those with inside knowledge do you know in a TL Verada whether there is a difference between the clock spring in the Xi (with steering wheel mounted audio controls) and a standard verada (AWD included). I am trying to find this out as I want to run cables through the steering wheel for tiptronic control buttons. Any help would be most appreciated!

Got a strong feeling they are different.

Maybe ring up a dealer's spare parts and ask them if the model numbers are different?
