True that would be a very clean way to do it and honestly aside for another cost cutting step I can't see why they didn't include it. The only thing that's been holding me back so far is the unknown of what is needed and the expense. Both if the new door wiring harness is needed which is required for the towing mirrors and/or if the ECM needs to be reprogrammed.
Looks interesting, the other wireless options from carplaykit etc. seem to be hit/miss on how well they work, and of course they don't offer any increased functionality just wireless connection. That said $600+ is pretty steep.
Bump in case anyone has figured this out. I'd like to add a Ram mount tough track onto this piece just to do something useful with it, because I never use it for anything. Everything I want to put it in is either too big to want sliding on the dash, or too small to be seen when it's in there. Very odd item to me, not sure what GMC was thinking with these. https://www.amazon.com/gp/product/B071CK5TJW/ref=ox_sc_saved_title_5?smid=A2XENS8LQP1A6D&psc=1
Unfortunately their only response was that they have no plans to offer anything, but would pass along the interest to the engineers. So I guess for those that read this give them an email and if there's enough interest maybe they'll make something. I had hoped they might have some info as to what is needed to do the upgrade but no luck there. I still think a set of mirror caps that had plug in capability to add turn signals would be a good seller.
I emailed Boost on this since they have some mirror wiring harnesses and mirrors they do for the 2019+ Sierra's to see if they have any input on what is needed. It sure seems like the small mirror caps would be a perfect platform to add turn signal LED strip lights to and a kit that does something like that would be right up their alley. I'll post what I hear back.
So sadly while packing everything under the sun into the 2020 1500 mirrors it seems turn signals lost out......no idea why, cost cutting most likely. That being said, has anyone tried to add turn signals to the factory mirrors? Seems like at least there's the capability for them as the optional tow mirrors have turn signals in them, but they do require a new door wiring harness so perhaps that would need to be added as well. It might also require programing as it says for the optional tow mirrors the BCM has to be reprogrammed, but it's hard to say if that's for turn signal function or something else. Don't really need them, just thought it might be an interesting mod if it doesn't require giving a dealer $$$ to reprogram a BCM and the wiring hookups are there.
Wish they made a model where the step extended rearward more, they look to be about 6-8" shorter than the factory ones, I never thought I'd really use them much but I do find myself now and then using it to step and reach into the tailgate for something.
I just did this mod, so far so good, I used the 5 coil version and soldered splices into the 12v in the rear of the console and used a 12v to 3amp/5v step down converter. It works pretty well but the factory unit has more "distance" to its charge, but the 5 coil charges faster. Replacing the rubber mat with something thinner would work better. Between that and adding a courtesy lamp to illuminate downward into the console from the lid when open the console is much better now. One tip for 19/20's as I found it hard to find this info (in fact I thought I found it in this thread), is to get into the rear of the console, you remove the rubber cup holders (they just pull up) then there's a torx screw to remove which allows the plastic molded cupholder part to be removed by pulling it straight upward, then there's another torx screw that can be removed, and then the rear console panel pulls rearward. For those that have 20's and I assume 19's and are worried about the battery drain there is a 50 amp fuse on the passenger side that has 2 positions (3 spades) if you move it you can have the 12v ports work as if they are accessory power instead of always powered. Fuse in question is circled in red, and it's current position is always powered.
I really like this little guy that might be the way to go, they make a little smaller 6 switch version that would be fine for me, I can't imagine ever using more than 4, but never hurts to have some extra.
I've been toying with doing the upfitter switches for awhile, but after reading some great install threads on them I'm starting to wonder if it's worth it -vs- just using aftermarket aux switches. Mostly because I don't like the fact the factory ones are labeled just Aux1-5, and I don't really see the benefit of the factory setup, especially since the control connections are not under the hood like Ford does. So I still have to run all the control wires from my devices through the firewall or into the cab, and behind the dash to the switches. If I was running a snow plow I could see it since one of the switches goes up to the third brake light. So perhaps I'm missing it but it just seems like there's little benefit. If they had some of the control wires run under the hood, perhaps one to the rear of the truck, I'd be more tempted. Thanks, Todd
A couple people have reported success emailing GM about it, ([email protected]) and requesting it be installed. I tried that back in May, perhaps they got wise to all the requests, and there response was that the app is no longer supported and as such will cannot be installed. In addition supposedly when those trucks that have it get their next software update it will be removed. That said if my 2020 AT4 is any indication (no update since March) they may never update the older ones If anyone has success with it now I'll have to retry.
Was looking at this after I tried another tailgate seal that was dislodged by a car wash (not sure if it was the undercarriage sprayer or dryer). Does this also act as a tailgate/bed seal when the tailgate is closed keeping crap out of the bed, or does it only work for that when the tailgate is open? Thanks
I concur with the AT4 seats. I couldn't feel them when the truck was new (2020, just shy of 2000mi now) and I can feel both alert vibrators easily through the side seat cushions and rides any longer than 20-30 minutes get very uncomfortable with them poking into your thigh/back pocket area. I don't mind that the seats are firm, but you can easily feel with your hand on the sides of the seat where the units are at, passenger seat is much more comfortable. I also agree the seats are narrow, I'd happily take a 2" narrower console and add an extra inch of width to both seats. Also for being firm, they don't actually hold you in the seat very well cornering etc. I'd take my 98' S10 seats back in a heartbeat over these, and they were 22 years old with almost 300k miles when I got my AT4.
2020 AT4 6.2, <1000 mi, noticed the same thing, I don't notice it at stop/starts or during driving but I definitely notice it if the truck has sat say overnight or during all day at work. If it's just in/out of a store it's still quiet. But yeah, mine sounds just like a bad pulley/slipping belt for 15-20 seconds and then it just goes away. Haven't tried to investigate to see if it's the exhaust flapper as some have found. It has a few gremlins so far 1) said squeal at startup 2) Hard/delayed shifts from 1st to 2nd and 2nd to 1st (read disabling auto start/stop can help, but haven't tried it yet) 3) For some reason the lane departure alerts that used to vibrate the seat have stopped, don't think I change any settings but some alerts like car/person behind still vibrate the seat 4) Even though it's turned on in the settings, autostart will not engage the cooled seats. 5) Traction control doesn't really appear to be working, if it's raining etc. the system says it's on but it doesn't seem to engage, IE it's easy to spin up the tires on a wet road turning a corner. Also even if I follow the steps in the manual, I don't seem to be able to turn both TCS and ECS off, it only seems to impact the TCS.
