Does anyone have pics of their 2003 TL Onstar system. I am looking to see where they placed onstar in 03 and how it interacts (if so) with the navigation system. This is a mod I am willing to try in my 01 TL, but I would like to see pics of the onstar system in the TL. I want to know if they installed it on the rearview mirror, or the buttons are on the ceiling. Thanks

 

the buttons are on the rearview mirror.....you can't MOD onstar into a vehicle....it only comes from the vehicle mftr
