I want to install NAV in my 2011 GS but would prefer to go OEM, the problem is without either a number off the NAV radio tag, or the last 8 of the VIN of a car that had OEM NAV it's impossible to get one. All the dealers I call, or companies that refurbish OEM units and even "used parts" yards (commonly call Junk Yards) will not say for sure a unit they have will work properly. I'm not to concerned about the voice commands but I want the On-Star, Bluetooth (without external microphone like the Alpine, Pioneer..etc use), steering wheel controls & XM radio. More then one dealer said that without the tag number they can't guarantee it's fit to the harness, and will not take it back, and the dealers "cannot" confirm, they say, what is the right unit for me to give the number to some other company (the dealer wants over 2K just for the head). What I'm looking for is either the number off somebodies OEM NAV radio or the last 8 of their VIN so I can at least get a dealer to look up which unit it would have been produced with. Can anybody help me with this information??? I don't want anybodies VIN but the last 8 are all the dealers need they say.

 

I would call Gm Parts House...They list a nav unit on the website for your vehicle.

I took this from one of there post here on the forums:

gene@gmpartshouse.com or Patrick, patrick@gmpartshouse.com, or give us a call at 484-949-2099.

 

Who do you think told me to get this information..and the nav system they show on the website is now $2800+ instead of what they listed. Also when I asked what was included for the $2800+ price they told me they had no idea, they don't package them it is done by the company that does the radios

 

Not knowing anything about radios, I go to the experts, I know with XM radio you need receiver that separate to the radio, to make XM work, same with Onstar, so here is vender on the forum can answer all your questions, ask for Dennis.

One of the advantages of getting older is being able to tell when you're being jerked around. And you, my friend, are being jerked around.

Year before last I bought a 2011 coupe that came with a Bose radio. Even though I wanted the OEM NAV, I went ahead and bought the car believing the NAV could be bought later.

My first action was to call my local dealer (I've got a good relationship with my Service Tech) and the best price he could get me was about $3,000. I told him that I thought that was nuts and asked how much for installation, if I brought him the car and a NAV unit. His answer was $800 claiming the need of an expensive connecting cable. I told him, "No thanks," and continued on.

For about $500, I bought a NAV off of the CF Sales Board, that was taken out of a 2012 GS. I figured that if it didn't work in my car, I could put it back on the For Sale Board and get most of my money back.

The other thing to note is that the member that I bought the OEM NAV from had left the OEM GPS antenna in his car and had hooked up his new Kenwood with that antenna. As a result, the GPS antenna that I got with the OEM Nav was the unused Kenwood antenna.

I took this used OEM Nav, the Kenwood GPS antenna, and my car to a local auto audio guy and had this stuff installed in may car. I was plug and play. This guy took enough of the center console apart to do the radio-ectomy, swapped the radios, and put my dash back together in an hour, which included figuring out how to mount the USB connector that my car had lacked with the Bose radio. We wound up removing the ashtray and mounting that connector behind the ashtray door Everything worked as expected. But when we started the car up the radio security locked up the radio.

So, I drove my car over to the dealership and showed the Service Tech the installed radio and told him I need him to apply the magic tool to unlock the radio. He was amazed. Took my key, drove the car around to the service area. He came back in about 5 minutes with the radio working.

He felt so bad about being so off-base about my radio installation, that he didn't even charge me for unlocking the radio security.

So, if I were you, I would buy a OEM NAV from a 2011 or 2012 vette off the C6 Parts For Sale board. It won't matter whether it comes from a narrow body, GS, Z06, or Z51. Find a local audio shop and show up with your car and the new radio. If that shop has any C6 experience, the radio swap is plug and play. Then, all you have to do is find a dealer with the tool to reset the security system. They may tell you that they need the VIN of the car that it came out of, but the truth is that they don't. If they are worried that the radio was stolen, just take some printouts of the emails that are generated in your purchase transaction.

Good Luck with your journey.

 

Do you CURRENTLY have OnStar, BT, and XM in your car?

If not, go aftermarket. All of the oem parts, harnesses, and labor will cost you as much as a new C7.

If you DO have everything except the Nav HU, then you SHOULD be able to do a plug-n-play swap, but the current XM box probably won't work on the new HU. You caould buy a new GM unit and have the dealer marry it to the HU when the marry the VIN to it, or you can get the SIRIUS conversion box.

GM p/n off the Nav HU I took out of my '12 is 20856087, XM box p/n is 28045272
