FYI for anybody that want to take a different approach to solve this. I’ve bought a Fakra K female to Fakra K female extension cord and guided it from the new antenna xm connection to the radio xm connection. If you replaced/upgrade your radio module before you will know what you need to do to access it. Otherwise you can have a look at the HMI/radio upgrade sub forum It worked perfectly and now I have the new type of antenna with xm and and no reception issues This is the cable i've bought: https://www.ebay.com/itm/13FT-Fakra-K-Female-to-Fakra-K-Key-Jack-Cable-GPS-Radio-Neutral-Coding-Car-4M-/264864203606?_trksid=p2349624.m46890.l49286 Depend on your vehicle you can probably get a shorter cable but I played it safe with a few extra feet just to be sure

BTW, all other screens in the dic work just fine. Active cruise control is also operational.

So while I was driving down on a highway my dic information screen suddenly started blinking and than disappeared. Since then, it randomly disappears and appearing back. When not working I’m getting parking assist not available message (only when it should work not while driving etc) Ive also notice that the exterior temperature on the infotainment screen is not working as well. anyone else had this issue?

Thanks for the input. My bad on the AFM cylinders. It's number 1,4,6 and 7. I have another mechanic inspecting the engine next week to get a second opinion. If he will recommend a compression test I'll go ahead with it. I'll keep this post updated

Hi all, 15 Yukon SLT (94000 miles) here So I had a misfire code P300 and engine light blinking late December 18. Done a tune up (replaced all sparks and wires) and everything was fine until a few days ago. Didn't feel any lose of power, vibrations and etc. Got another misfire code, this time P0305 (cylinder #5) a few weeks back. Mechanic looked into it and couldn't reproduce. Had an engine carbon clean up. Again no lose of power, vibration poor fuel economy and so on. Couple of days ago got another misfire P0305. Called the mechanics and he suggested a compression test. Not sure if needed as no other signs are apparent. He also start speaking (worst case) about taking the cylinder out to be inspected and replacing AFM lifters. I've looked into mode 6 on my OBD scanner as saw that cylinders 1,3,5,7 all have misfires, though below the threshold so no codes or lights. Cylinder #5 had count of 78 misfires and the rest (1,3,7) around the 1-5 (thats after a 2hr drive) What I found weird is that the AFM cylinders (2,4,6,8) had no misfires. Aren't those the ones with the lifters? I've replaced the coil of cylinder 1 with 5 and got the same results (higher counts of misfires on 5) so don't think that is the problem. Anyone encounter the same issue? How was it solve? Any suggestions for self diagnostics before its heading back to the a shop? Thanks

Maybe it’s an interference from the new module. Try a different location as see if it still happens. Good luck

Did you had navigation before? I had issues with gps signals with my iPhone when it was placed close to the screen (like the front cup holders or inside the hidden compartment) when I’ve placed my phone on the center console or near the windshield it’s working just fine. Im with a 2015 yukon myself which had factory nav before I’ve upgraded to CarPlay

Hi, any tips on how to remove the seat back panel?

Thanks!

Do you have a link to that video? I would like to try replacing this pads myself. Did you also replaced the back rest element?
