Dennis this was from an old post, not sure it's the same for 2006!
Rexx, my Alpine is a 2003 and 2 years ago I replaced my*steering column*clock spring for VIP Smart Wheel made by Douglas Autotech Corp -*http://www.douglasautotech.com*-
517-369-2315. The part was supplied by WRV but I did receive tech support from Douglas Autotech.
I was able to prove to WRV that the clock spring had been installed incorrectly in order to cause all of the wires in the clock spring to break. First, I started experiencing an occasional cruise control problem, then other problems, which got progressively worse until all functions controlled by the smart wheel stopped working.
The information I received at the time was the Control Unit was SM209 & Clock Spring was part #1900043.
