I definitely understand not wanting to rip apart the install to document it as that could mess something up. I will do my best to do the install myself and when I do, I will document it to make a step by step to possibly merge with this thread. Haven't located the pinouts in my service manual (it is huge but not GM-made) so I am still searching.

    From what I gather, the nav head unit plugs up and powers on just fine, so the display is the only thing I have to supply IGN/ground to?

    Finally got the funds to purchase my set up so I will be doing that tomorrow but I'll be missing a couple things like the GPS antenna for right now. But that seems like an easy part to add in there later. I really just want the nav for the touchscreen interface. My Chrysler 300 had an 8.4" touchscreen whether or not you had nav and using this scroll knob to sort through my music is so annoying!

    One generic question I have about the wiring is, I've never soldered before so is there a way I can splice wires and attach them to the connectors without having to use a soldering iron? Such as crimping.

    The help is much much much appreciated. Hopefully you won't want to kill me after all my questions! lol
    That's no problem at all. I'm always willing to help if needed. I'm currently doing a write up that I'll try to put in the DIY section. I've gotten alot of questions on the swap so hopefully that would be clearer to people. But, I do recommend that you try to buy a complete takeout out of a wreck or salvage yard. All the supporting pieces you'll have to buy (gps antennae) could break the bank. Also, before starting, you'll need to have the radio unlocked. You wouldn't want to install it and get the dreaded "locked" screen (like I did). To answer your question, I do recommend soldering (and heat shrink). This creates a permanent joint. Crimps can easily fail if not done right and can be a pain in the ass to troubleshoot.

    Re: Successful navigation swap into a non Nav CTS

    Guess I'll have to learn how to solder then! I have found some great deals on the screen + head unit but some without harness and all without GPS antenna. For the time being I would be fine with no working nav until I found an affordable antenna, as this is mostly so I can navigate through my music library much easier. I think the antenna will be simple to install (unless it requires wire tapping?)

    Was reading the thread again and looking at the pinouts/schematics...since I have the 10-speaker system I'm guessing I won't lose the door chimes/signals/etc and have to re-pin? Seems like all I have to do is:

    Power and ground the display
    Tap into VSS for nav, which is optional
    Run a shielded wire for voice guidance

    If I'm missing something please let me know. So 1968vert when you found the VSS wire where exactly did you run it to? I'm talking about which connector and pin you used. Looks to me like number 20 on "radio x4" 20-pin connector but just want to confirm.

    Rudeboi can you tell me from where to where you ran the voice guidance wire? Is it just one single wire? Needing to know from both ends, which connector and which pin because I can't tell from the pinout screenshots.

    Re: Successful navigation swap into a non Nav CTS

    Can you look at the pinouts on page 2 and 3 and find where it went? I was looking for something labeled "voice guidance" on those diagrams but didn't see anything so it must have a different name. Or I overlooked it.

    Re: Successful navigation swap into a non Nav CTS

    1968vert have you seen the write up/DIY on the reverse camera install? One of the posters included 2 PDF pages with instructions, where they tapped the wires, what parts they used, etc. If you could do something like that it would be perfect. I was able to fully understand that one.

    The navigation voice guidance is 2 wires(-+). Audio amp x3 pin5 navigation audio signal- and audio amp x3 navigation audio signal+ pin13. That is on the amp.

    Radio x4
    Pin7 nav signal + and pin17 is -

    Now if you want voice recognition that would be something else. I did get mine to work. I had bluetooth before the install and i can say comands and the radio would do it. I had to run a shielded wire from overhead console to make that work. I hope this helps because to do a write up is impossible at this time. Ask questions and i will help.

    Ps
    Don't use those wire clips because I ran into that issue. 1968Vert is correct on that.

    Re: Successful navigation swap into a non Nav CTS

    Thanks very much. The pin info you gave was exactly what I needed. I don't really care about voice recognition as I have had that in all of my vehicles and never once used it.

    Waiting on a phone call to order my radio, screen, and hopefully the harness now.

    1968vert do you remember which pins you used to ground the display and on what connector? Didn't catch any info on that.

    Re: Successful navigation swap into a non Nav CTS

    Got such an awesome deal on the setup. Bought the radio head unit, screen, screen trim cover, all harnesses (that can be removed, and pigtails where they couldn't remove wiring), nav faceplate, and all matching trim for $365. I asked for the matching trim because this is out of a CTS-V. So not only will I have nav but now I'll also have the glossy black CTS-V interior trim. Very excited about this install.

    Re: Successful navigation swap into a non Nav CTS

    Yeah $1200 still is awesome for nearly $3000 worth of parts + labor costs. I'm hoping mine comes with the GPS antenna, if not I'm sure they'll give me a great price on it. Gonna start writing down some instructions for myself based on the info here and should be able to tackle the project soon.

    Did you guys use any terminals for the wiring when plugging the wires into the connectors? When I researched the rearview camera install thread the OP used metal terminals to properly install the wires in the connectors. Wondering what you guys did whether it was that or just inserting the bare wire into the connector.

    Re: Successful navigation swap into a non Nav CTS

    Sweet deal, man! I thought my setup was a steal at $450. You do need the terminals. The connector pinout in the manual would have the part number of the terminals and connectors. I don't know if your manual is different than mine but my my pinouts were located in component locator file within the schematic folder. There would be a picture of the connector. below the pic will be the part number/tray number. Take the part number/tray number to the dealer, they should have them on hand. the dealer I go to just gives me the terminals. You'll have to pull the lock out of the connector to insert the terminal.

    That is correct, my pigtails came with extra and i just mix and match. I didnt pay for those nor the usb port in the armrest. My seller send me all the wires for the front of the car, the instructions from 1968vert and gm manual helped me alot.

    Re: Successful navigation swap into a non Nav CTS

    Okay, so I will notate their part numbers. I used the diagrams 1968vert provided as I hate sorting through my service manual (though it looks like we have the same one).

    Based on the necessary wiring info you guys have provided, shouldn't the radio and display power on before the advanced wiring is done? I want to make sure everything works before doing all of this and from what it sounds like, before I do any splicing, the radio and screen, running off the factory harnesses, should still: power on, produce audio and video/picture. Sounds to me like we are just adding up/down signal for the display, VSS for nav, and voice guidance, so everything else should work beforehand, right?

    Re: Successful navigation swap into a non Nav CTS

    Also what all screws/bolts/clips did you guys have to get in order to get the screen installed? Are there sufficient bolts just using the previous ones or are new ones needed?

    You have to be creative with that part. I went to autozone and brought bolts.
