it should work... only when you open the door I would assume. it wont work once all doors closed

Sounds like something has shorted out, if you ever find out what its causing it, I would love to know. Maybe I can make a button to turn the camera on demand. If it is 2021, is it still under base warranty? Would you be able to request the dealer to document what is causing the camera to come up?

I saw that OEM puddle lights are weak for GMC's, these from aliexpress are soo much cooler! Link to the product: https://www.aliexpress.com/item/1005005016639037.html?spm=a2g0o.order_list.order_list_main.5.145118023wFYsX Snapchat-298134928.mp4

Mine was off completely, no idea when it started. I had to bring the vehicle in to the dealer and had a VPCM or something like that replaced. Following is before and after. Not perfect, but a lot better.

Even without supercruise, my 2020 At4 ACC was all wonky when I used my old winter tires from my 2014, they were just a tiny bit smaller. The tiny amount of the tire size different made ACC uncomfortable to use. While working with OpenPilot (3rd party driver assistance), we ran into issues where we noticed the height could throw the model off, the scaling of the current model is designed for small cars, higher cars suffer from cutting curves too much, the speeds of the car you are following completely off. With these experience, I would expect SuperCruise will not be a good experience or may just not work at all if you changed the height of the vehicle too much. Without access to modifying the parameters, I would say, dont do it.

25 minutes usually is ok, but when you do long trips, this thing is amazing. It is something you have to experience to understand the value of it. Another reason why SuperCruise is only available on some highway. OpenPilot will work in heavy traffic as well, takes some effor of keep accelerating and braking over long period of time. I know it can be subjective, but there is no denying that micro adjustments during drive is part of human input. Over time, needing to stay in a fixed position will fatigue. this is a fact, no need for arguments. I now have the freedom to stretch and move my legs around, this is a huge plus. I show up to work energized, not stressed out from slower drivers etc. But, if that is all you took from this write up, then I dont understand why you are browsing the mods or even appreciate the technological advancement.

pretty sure it is due to the chip shortage so they removed whole bunch of things. my 2020 AT4 has buttons for all four exterior handles.

If you have long highway commute each day, you will benefit from this! OpenPilot is a Level 2 driver assistance system, it enhances the garbage Lane Keep Assist (LKA) we have in these trucks. The way it currently works is introducing its own steering commands that the factory system accepts to provide minor steering adjustments to keep you in the center of the lane. (Its more than this, but this is the short version) Given that it is using the factory system to provide steering power, it will never exceed the factory allowed safety commands to rip the steering wheel out of our hands. Unlike may other OEM systems that follows the lane lines, this uses human taught driving to provide a more natural behaviour (can be seen that it hugs right on undivided highway for example). This system is similar to SuperCruise in the manner that it monitors the driver visually for any distractions, this means it is a true hands-free experience for majority of your highway driving. Currently, OpenPilot does not control the throttle and braking, it is still handled by the factory ACC system. This is a very reliable setup, but eventually, it will take over gas and brake to do amazing things such as cut-in mitigation. Here is a short video of it in action: I am one of the few first hand users for this system, it has dramatically reduced my driving fatigue for my daily 25 minutes commute. Few of the issues we have is that our vehicles are really tall, we need more driving data of a tall vehicle to "teach" the system to drive even better on this platform. Few of the possible features that is currently possible in the foreseeable future update includes: - Better Adaptive Cruise that slows down earlier and smoother than stock - Automatic Lane Changes without needing to nudge steering wheel (May require blind spot monitor signal implantation to work) - Stop and Go for automatically resuming from a lead car starts moving Things we probably wont see in this platform: - No full self driving (due to steering is not available below 10 km/h) Requirements: - 2020 or 2021 with ACC and LKA options - Comma 3 unit with GM Camera Harness (I believe it is immediately available now through purchasing on their site) and the black harness box - Trim tools (if you like to make things nice and pretty, Torx screw driver set with extended shaft driver to remove the overhead center console to hide the harness) Video explaining what you will need to get started: https://www.youtube.com/watch?v=rwDDid_bLrU https://www.youtube.com/watch?v=5HbNoBLzRwE

I have purchased Tow Ready 20142 7-Way as you have suggested from another post, this works flawless! Do you have a picture, part number or a link to purchase the curt connector you are referring to? I also want to do a switch, but maybe using the signal switch with relay, so they work without needing to flip a switch

I have heard people without sunroof sometimes can develop a noise when heated up and cools down

I guess this might be my issue!! I have been getting my left rear TPMS going in and out!!! Who has a better wire running path for the dashcam, yes, I am using the Viofi duo too

It has occurred to me to ask, what cab configuration do you have? Short box? I am suspecting the different box length would result in different mounting position for the prop rod to the plastic rail it sits in

Installed my Bakflip MX4 today, anyone had them propped up all the way against the rear window using the gimpy looking prop rods down the highway? They do not look secure enough to stay up the way the promotional instruction videos say

You dont have to get to the headlamps, use the pins at the BCM, you can find the pins you need by looking for the fog light on with highbeam mod, same wires for 2014+, this will save you some time
