I would like to change the factory rearview mirror that is in my 06, which doesn't have the auto-dim mirror to one that does have the auto-dim.. I seen one on e-bay that says it fits my car, but was wondering what all would be involved in replacing it.. I had it in my 03 but it wasn't in the 06.

 

a couple of plugs n some sliding off the bracket on the glass i think.

 

I wasn't sure if with it having the auto-dim mirror, and my current one not having the dimming mirror, if there would need to be an additional wire or two to be ran to activate that part or not.

 

there might be casue now that i think about it is there even any power to the mirror?? the compass and temp is in the dash. im used to the burbans and stuff in the mirror. wait there are lights so then there is power to it so...... it might be invloving finding the 12v hot wire then a ground and some quick splitting. id hope. (i was thnking and typing)

 

Yeah there is power going to my current mirror because, like you said, it does have the map lights on it. Also, I do have OnStar, Emergency & the Phone button on it too. So there is power.. There is a thick black cord that has the wire harness attached to it in the back.. I think what I may do is call the dealership tomorrow and ask the service dept. if there is any wiring difference if I were to buy the auto dimmer.. I hope not because that would be totally awesome!! I miss it from my 03 MC

 

sounds good to me. let me know how it works. with so many cars having the hid headlights now the tint isnt doing much. so i may get one if its that easy
