    Ideas about the Rear-View Camera for 2008-2010 CTSs

    Hey Everyone,
    After following the thread at http://www.cadillacforums.com/forums...-nav-disc.html, it's quite evident that the latest NAV software update contains the provisions for the rear-view camera.

    I have not performed this mod (and don't even know if it'll work), but I thought I'd pass on some information I looked up that might help someone else find a solution.

    I'm 99% sure the Nav hardware unit (AKA the GM Silverbox... you can see here: http://www.sandyblogs.com/techlink/2...stack-ics.html) is identical for 2008-2011 CTSs. That leads me to believe that the inputs existed, but were never used.

    I looked up the pin-outs in the Service guide for both the 2011 and 2008 CTS.

    There is a 20-pin gray connector that attaches to the back of the nav unit. This connector has provides various audio and voice inputs to the nav system.




    Pins 5 and 15 provide signals from the rear-view camera to the system (Circuit 6972 and 6973).





    In the 2008, I checked Pins 5 and 15, and noticed something interesting. These pins are not listed as NOT USED (such as Pin 12), but rather as COAX, as well as wiring colour. This leads me to believe that these two circuits are undocumented, but exist (In the pin-out list, there are other COAX connections that lead to other components in the car, such as the USB input and Nav display).





    The big question is: Is there wiring already place that terminates to these pins, or would new wiring need to be installed?


    I also checked the pin-outs of the camera. The 2 camera circuits (6972 and 6973) directly terminate to the camera. This tells me that there are no other components to the camera and the camera is simply providing an analog video source to the to the nav system.








    Something to note is that along with the ground/drain wires, there are 2 other circuits that would have to be tapped: The Backup Lamps Supply Voltage (most likely to indicate when to turn the camera on), and the Ignition Voltage (so the camera is only powered when the vehicle is on).

    So this leads me to a couple questions to anyone wants to look into this:

    Does the wiring harness in 2008-2010 vehicles already include the 2 wires for the rear-view camera?

    Are the other circuits the camera requires, already available in the rear of the car?

    Hopefully this may help someone eventually install a camera in their car.

    Re: Ideas about the Rear-View Camera for 2008-2010 CTSs

    I Want to do this!
    I Do know as is with the old software on my 08 It already knows when its in reverse You Can see this in the nav service menu
    It looks like the OEM Camera is $264 on GM Parts Direct
    Hopefully All we would have to do is send the Camera signal to Pins 5 &15 and Just power the Camera off the reverse lights, Along with the software

    I Found some cheap eBay $30 Cameras that replace one of the license plate lights Maybe we could try that first

    Id be willing to try it if someone has the software for me

    I'm working on this mod now. I just got the 2011 rear trunk applique with camera assembly for my 2008 (thanks to some friends). From what I can see the assembly is a 90% interchangeable. I work in vehicle wiring, this mod is possible but it is not only wiring it needs radio programming too (verified by guys that know), stay tuned.

    Re: Ideas about the Rear-View Camera for 2008-2010 CTSs

    Just a quick update for now. I finished this mod last weekend and had the dealer turn it on in software yesterday. It works perfectly, and acts just like a 2011 would (nav screen pops up in reverse with cam and goes down or back to radio in forward gears).

    I'm going to write this up in detail but this mod is definitely not for the novice. It involves running 6 new circuits in the vehicle that are not there on an 08 (which requires removal of the driver and rear seats, and nav radio). Also the 2011 trunk applique with camera is an exact fit but requires two new holes to be drilled into the trunk (they slightly changed the location of the studs that hold the applique on). The dealer then has to recalibrate the nav radio in TIS2WEB to enable the rear camera.

    I hope to have the details up this weekend.

    Wow, impressive information. It appears your connected to the right people to make this mod happen. Would regular joe's be able to do this? As in get the parts, and the required software, or do you need someone on the "inside" to help you? Is there any other audio or video input in this unit that are no in use?

    Re: Ideas about the Rear-View Camera for 2008-2010 CTSs

    Excellent question, as I started hashing through the details of what I did, I started questioning how many would be able to do this. At it's heart, there were three steps: 1 mount camera, 2 run new circuits in car, 3 have dealer enable camera. The difficulty with this mod is in the details for example, I chose to replace the whole rear chrome molding with the 2011 version that had the camera already installed, this made the camera mounting look nicer but required new holes in the trunk and modification of the wire harness in order to fit the larger connector through the trunk hole. Running wires in the car sounds easy but requires removal of the driver seat, rear seat, nav radio, and surrounding trunk and vehicle trim to do it right. Attaching to the various connectors requires someone to have access to the needed connectors unless they want to start cutting off connectors and just soldering the wires together. Getting the dealer to turn it on was the easiest part, it only took 5 mins to program it.

    It is a difficult mod and I am really not sure who will be able to do it.

    Those who attempt this should feel comfortable with either the risks involved or the level of difficulty. If you haven't done these sorts of mods, it might not be a good place to start or it might be good to team up with someone who has. I have been doing this sort of work for quite a while. I have a few questions, csalmon. Where did you get the connectors? Where did you run the ignition voltage circuit?

    I would be comfortable with the electrical side of the project. Can I just pull into a dealership and ask them to update my NAV Unit with the latest & greatest software? Will they? What would they charge? If I just order the 11' NAV disc, would this update be on the DVD?

    Sorry to be houding you ... but would you be willing to share your knowledge of the wiring side of this project? I'm going to be pulling my infotainment system out to put the lockpick in and at the same time would love to enable the backup camera. My CTS has limo tint all the way around and a camera would be sweeeet!!!
