I am trying to figure out what the small module in the center stack is. The part number on it is 3yg06791. It came with the 04 center stack I bought for the bose. My 05 SE doesnt have this module.

 

Pics please...are you talking about the menu settings, trip mileage etc...?

 

it's located behind the radio faceplate. Above the stereo. There are white modules screwed into the metal frame. Mine has one white module the 04 center stack has the same module as mine but another small white one.

 

I noticed those when I moved my info screen. Someone on here posted about them before... cant come up with anything though.

 

I think I found it. It might be the automatic drive postioner. Something for the seat and steering wheel in a sl.
