A while back I was trying to set up the two step feature on the emanage ultimate. I didn't have any luck. Today I think I figured out why. When i am at a spotlight, my speedo is bouncing up and down between 0-8 kph, and on my car stereo the reading is doing the same thing.
So where is the sensor? Anyone have any ideas what would cause this?

 

I'm under the impression that in the 5.5, the speed signal comes from the ABS actuator. There is no sensor in the transmission/differential any more.
