Aaaaaaaayush

That is definitely not for the rearview mirror, My truck has that connector clipped up as well but it is connected to something under the plastic trim around the mirror bracket, it might be for a security sensor or something, I'm not sure but it was already connected and used. The rearview mirror connector should be more square than flat rectangular and it should be glued to the inside of the headliner. The easiest way to be sure its there is to remove the overhead console (lights, garage buttons, sunroof buttons) there are two T-screws up there under two small pieces of trim, after removing them the console should pop out and you should be able to see if the connector is there! I believe part 9 is that sensor under the trim I'm not too sure what its for though.

Waking up this thread for anyone who has still has their CPlay2Air and/or Carlinkit (They are the exact same) and still have not gotten it working. When I went to update the dongle, the highest version it was giving me was 2020.10.28 but I figured out you can manually flash the firmware using a usb flash drive. I AM NOT RESPONSIBLE FOR ANY MESS UPS YALL CREATE, Flashing firmware like this could Brick the dongle and make it completely useless! Here are the steps to Flash a higher version of the firmware 1.) format a flashdrive of any size (USB A) to FAT32 2.) Download the firmware from https://github.com/ludwig-v/wireless-carplay-dongle-reverse-engineering onto the now formatted flashdrive, I Used the Custom 2020.12.10 and it works perfectly for my truck (Make sure to rename the file to U2W_Update) 3.)Connect the CPlay2air/Carlinkit to a USB wall adapter, wait for the solid red light 4.)put the flashdrive into the usb port on the dongle (red and blue light should start flashing back and fourth) 5.) GIVE IT 5 MIN to finish flashing 6.) Solid red light should appear when finished 7.) when finished, unplug the dongle from wall adapter then remove flashdrive from dongle and plug into Silverado!! should work great! If red light doesnt appear you may have bricked the device and now it is garbage. (still try it out) here is a thread I read that might answer any more questions you have (page 187): https://forums.macrumors.com/threads/carplay-adapter-to-convert-to-wireless-carplay.2193978/page-187?post=29208724#post-29208724

That is definitely not a software issue! It seems like the camera might have shifted in the tailgate button module. Ill take my tailgate apart tomorrow and see if there is any camera adjustment of any kind. (My camera is perfectly centered, but that seems rude of the service department to dismiss it as a software issue.)

Good luck, I assume its all the same(same body style). When you order it they will ask for your VIN and when they realize these parts aren't for your truck they will ask you if it was an intentional mod or if it was an accident. They will still send it to you, I just said it was intentional mod.

It was all plug and play, the mirror does all of the video processing itself, no programing or BCM reflashing or anything like that. Headliner kit was $200 from amazon there are plenty on amazon just look it up, I have a 430 piece kit its like 16watt its pretty bright. here are some pictures of it while I was installing it, obviously I cut all the fibers flush, and I installed the light box behind the rear seat and ran all the fibers up the C-pillar. Ill take some more pictures tonight.

PN: 84699124 is only the high mount lamp (FOR GMC SIERRA) with no harness, no mirror, etc. I think what Kyle’s AT4 was talking about was the “infotainment.com” upgrade which is all packaged together but costs $1199 My PNs were all for a 2020 Silverado LT Texas Edition, my high mount lamp came with no harness and I would need a new harness that had the coax connector for the video signal. I ordered all of my parts from “TascaParts.com” which is where I found it to be the cheapest, I didn’t want any “take off” parts or used parts so these were all ordered New genuine GM parts. My Subtotal was $771.90 and after shipping and taxes the Total came out to $870.37, I believe this was the cheapest route for me without buying used/take off parts. Subtotal: $771.90 Estimated Shipping to Austin via Standard Shipping: $32.15 Tax: $66.32 Total: $870.37

Sorry I've been busy recently and haven't been able to update y'all but I did finish in about a day, I did also do a Rolls Royce Starlight headliner so that added to the time it took me to do the mirror (because I didn't have the headliner harness in). It isn't necessary to remove the whole headliner from the truck, however I did because I wanted to do the starlight headliner and sound deaden the roof with Killmat deadener. I didn't have any problems, I was sure to glue the coax cable down to the headliner so it wouldn't rattle with music and also used some outdoor silicone on the bolts for the spoiler and the third brake light to reseal the cab and prevent any leaks. Everything worked perfectly no misalignment or anything like that. There wasn't really anyway to show you how to do it but there is a video somewhere in this forum from Infotainment.com that shows you the install, that kit is $1500 and I don't think its worth it just to have them in one box, just order them separate from gm parts suppliers, its way cheaper. I do have a toolbox that isn't low-profile so this mirror camera system was a great upgrade.

I ordered all four parts, P/N: 13536995 Mirror P/N: 84487008 High Mount Lamp P/N: 84335461 Cable P/N: 84599550 Harness Just Shipped this morning, I should get it on Friday and installed on Friday or Saturday. I'll Post again with any problems or tricks I come across and pictures.

Did the diode and 1000uf capacitor work for the relay chatter?
