Has any one installed the factory touch screen gps system?
I'm thinking of doing this but not sure what is involved beyond the physical installation. Is there any programming or initialization involved?
Where does the ant go?

Thanks

 

It can be done, but it's much more expensive than buying a 3rd party GPS and sticking it in the dash.

You need a new windshield, wiring for the GPS antenna, and reprogramming.

GM does not support post factory installs of the GPS.

It has been covered here ad nasaum.

 

One of the issues may be HUD integration - assuming you have a HUD. It may require wiring that you don't have. Also, the antennae are in the side mirrors.

You may want to look into one of the aftermarket units like the Pioneer. A few on this forum have that unit installed.

 

Sounds like to much trouble, I have HUD and wheel audio controls and like the Idea of the interface. I wanted to see what the options were.

Thanks

 

I do have HUD bose and wheel controls in my 07. I want a system that would interface so I thought the factory nav unit might be the thing.

Thanks for the help

 

The HUD does not require a new windshield, period. We have been adding head up display systems to C5's without the special windshield since 1999. The standard windshield is acceptable for all situations with the exception of direct sunlight and glare conditions which is probably close to 99% of all use. With that said the HUD is slightly more clear and better in those 1% situations if you have HUD enabled windshield.
To the O.P., the GPS system is integrated into several systems in the car beyond just navigation. There are two different methods it uses to verify movement as well as whatever interfacing needs to happen to get the turn by turn in the hud along with the MP3 and radio information. It can probably be done but not likely worth the cost. Dollar for dollar you would do much better with an aftermarket install of an AVIC or similar unit which can be had for a decent price and the features and guidance many would argue would be better. You of course would miss out on the integration with the HUD but this won't likely cost justify as you begin to examine the cost of such an install. The other problem is that the unit is "tied" to the cars electronic signature so you would need to purchase a new OEM unit and wouldn't be able to get one discounted from say one of the auction sites or the like. Even those of us with the Nav unit can't simply swap one for another in the event of a problem. It will need to be activated to work with the specific automobile.

Paul, I said GPS not HUD! GM uses a seperate part number for windshields with GPS.

 

Actually, you didn't say either. You simply stated that he needed a new windshield. I however made a rush assumption and I'm sorry about that. Since the Nav cars must have the hud for the integrated features I'm certain that this is the reason for this. It likely comes as a HUD windshield preassembled with the Nav antenna attached so it doesn't need to be done at the factory.

 

Actually, the Nav GPS has no connection to the windshield. The antenna is located in the dash, just above the center A/C vent (it is accessable with the console trim removed). No special windshield is required. You may be thinking of the OnStar antenna, which is clipped to the windshield frame behind the passenger sunvisor.

 

The XM antennas are in the mirrors (of 2006 and up C6s). That has nothing to do with the Nav per se. Those antennas connect to the XM module (if present), which is located behind the driver's rear trim panel (in coupes) or behind the waterfall panel (in verts). Communications with the HUD are over the car's Class II bus, any HUD equipped car will have the necessary wiring.

What is different with the Denso Nav versus the Siemens 6 CD HU is the connector pinout of connectors C2 and C5. A small amount of rewiring will be required to make these mate up.

 

I just checked my shop manual....

Right you are.

 

Talon90 touches on the only issue of consequence when retrofitting a Nav HU to the C6. That is the GM theft deterrent programming. If you acquire a used Nav HU, it will have to be returned to Denso to be cleared so it can be mated to your car. The dealer can't clear it. New or used, a Tech II will be required to introduce the HU to your car and set up the anti-theft handshaking. A dealer can do this with a new unit, or with a unit that has been cleared by Denso (they basically reset it to new).

All of the other issues people have raised are either incorrect, inconsequential, or involve trivial wiring changes.

 

Thanks shopdog, I always screw that up. I get them confused as my car as onstar, XM (wart) and Nav so I've got the whole junior woodchuck survival kit.
