Default Rearview Mirror Upgrade

Hi All,
I am a newbie to the site and have recently purchased a C6 LT1. Does anyone know if the rearview mirror with compass is a plug and play for a LT1 package. I have reviewed the sunvisor upgrade threads relating to homelink and plan to make that mode soon and relieve my sun visor of the clip on garage door opener. I believe even the newer non homelink will be fine for me. I did not find much on the rearview mirror. I have seen several for sale at a reasonable price here. I believe they had on-star also. I have ordered the manuals and hope to find schematics, they have not arrived yet. Thanks in advance for any information on the subject.
Thanks,
TLCJ

Hey Terry. I am originally from the Maysville, Ky area just up river from you but have been in Florida for 20+ years. Please post your findings on the mirror, as I am interested in the same thing. Thanks!

Will do Ken,
I have seen a reference to a compass and auto dimming mirror w/o the onstar as well. There is one for sale with onstar in the parts thread for $130. Not sure that would be plug and play. Maybe an extra module somewhere. I am from Florida originally on the east coast. Satellite Beach. LOL

The 05 and 06 are different because of the air bag indicator...dont know about the 07.

Connectors might be the same...someone else verify...

I did it on my 2006. Turn the old mirror a 1/4 turn, unplug the wires and reverse the process to install the new one.

It's a small world isn't it?

Re the Onstar, I believe it also has to have an antenna. I am not really interested in the Onstar portion. Please keep us posted.

Well timd38 did it. Was that a 2006 or 2007? Did you buy it new or get one off a wreck. Did the new one have on-star and the old one did not? I received the manuals this afternoon. WOW. Schematics all over the place. I guess I was spoiled on my big one page schematic for my 72 stingray
Here is what I get so far
1 white controls map lights when you open the doors etc.
3 tan/black and 4 pink deal with the SIR lights(Air BAG lights)
5 and 16 I do not have and are for the outside dimming mirror.
9 i do not have and goes to reverse lamps???? Any ideas?
13 is pink and is power
8 is ground and black
I understand 2005 won't work because of the SIR lights. Just would like to know what my options are if a 2006 is parted out with compass and dimming and onstar or not. I will keep looking through manual.
I don't see the compass anywhere in manual yet. No onstar schematics either. I will keep trying. I have also sent a note to gmpartshouse for options. I have a message waiting there, but I am unable to log back in due to security. Will try from home tonight.

Thanks timbo79,
I read all of those posts before asking my questions. Just the proper thing to do on any forum. As I said earlier, I have contacted Gene as well for pricing and availability on a new one. There have been several for sale on this site in the other sections with the onstar capability. I know the 2005 will not work with a 2006, 2007 car because of SIR. I just need as many details as possible before I make any changes. Nothing wrong with looking the schematics over. Still wonder why a backup light wire is shown on some models in mirror? If onstar is self contained unit, maybe I will add that in too. It was not why I started looking at it, but might be a nice tag along. Thanks

I looked into it, but not into the ONSTAR. Just me, but I am not sold on the Onstar, Big brother knows where you are!!
You can also add the integrated homelink in the visor. Gene has the visors for this as well.
Let us know how it works out.

Hi All,
Gene did get back to me and the mirror new w/o onstar buttons is available no problem. I was finally able to locate the schematics on the mirror with onstar and learned the following. The mirror is just 3 switches as far as on-star is concrned. The wires are pins 11,12,14, and 15. You could use these switches for anything you like if you were customizing. Since these wires are missing from my car anyway i could get the used mirror with onstar and it would work just fine as far as I can see (switches hook to nothing). These switches do have a small line resistor in series if you decide to play! I don't like switches that don't do anything but was considering hooking these switches to my 3 button garage door opener and killing 2 birds with one stone. I have all the details i need and want to thank all for their input. Especially gene.
Thanks,
Terry

Are the non Onstar cars pre wired for it? Can you replace a 07 mirror with compass with a Onstar mirror and have the Onstar work?

Ron, I believe you need more than the mirror to have a working OnStar system. While I am not sure what all you do need, I do know you need an antenna and some OnStar electronics. Hope this helps.

TLCJ says "9 i do not have and goes to reverse lamps..." At first look, it appears the dimmed mirror will NOT clear itself when one is backing the car.

Hi all,
Sorry I was away for the weekend. What ken said is true. I do not have the wires that feed the drivers outside mirror or the wire that comes from the backup system. That said, you can still add the mirror and the only real missing feature is when you go into reverse. Thanks for the info on the backup wire. I assumed that was the deal, but was only guessing. As I said earlier, the mirror with on-star just has 3 switches in it for onstar that run to other electronics through wires that are not in my harness. The wiring harness is different!
