  1. The dealer here is a 'volume' dealer that puts them on every vehicle the sell as a non-negotiable item, along with nitrogen in the tires and few other items. General Manager said it's to ensure at least a little profit on every vehicle, but I don't know, seems like the new version of 'undercoating'. At least on these, you can actually see that something was installed. Have you tried asking the dealer for the install instructions, or just talking to one of the techs? If they put them on all the vehicles like the dealer here, I'm sure there a multiple techs there that know exactly where they put them on each model.
  2. There should be a USB port in the same area that you can use for music. I have a 'thumb drive' in mine with 1000's of songs loaded on it. Head unit recognizes it, just have to select it as the input source.
  3. I get the same thing on my '19 AT4 as your first picture about half the time. Put it in reverse, no picture from the driver side mirror cam, followed by 2 seconds of blue screen when shifting back to drive. Started at about 6000 miles. Haven't had it in to get looked at yet.
  4. Looks like they can be removed, but the clip on to holes through the fender.
  5. Sorry for the delay, was goose hunting all weekend. Here are the pics that show the weatherstripping I put in between the 2 tailgate sections. Rained quite a bit on me this weekend during a 4 hour drive and I'm fairly sure the little water I'm still getting is coming from the space between the larger tailgate and side of the bed, not here.
  6. I have the Retrax ProXR and have been working on getting it as waterproof as possible. Most of the water I have is coming in through that gap between the 2 sections of the tailgate. I picked up this weatherstripping from Lowes and put some at the very top on the plastic cap between the 2 tailgates. That stopped a large amount of the water coming back there. I think I still have some coming in between the larger gate and the bed on the sides - still working on that piece. I also have a Rok Block tailgate seal, but haven't installed yet - waiting to get the water coming in from the top addressed before I seal up the main exit path for it. https://www.lowes.com/pd/M-D-13-ft-x-1-in-Expand-N-Seal-Foam-Window-Weatherstrip/1000460601
  7. You have to take off the plastic rings and then there is a 'release' lever.
  8. It is fairly close to the texture on the side mirrors, but far enough away that you don't notice a difference. The Aeroskin II texture looks to be a little bigger than the mirrors, but again, it is not close enough to the mirrors to notice unless you are looking for it.
  9. Actual pics of the Aeroskin2. Sent from my SM-N950U using Tapatalk
  10. Don't have a pic handy and I'm out of town so I can't take one till later, but I used my GM Points to get the Aeroskin 2. Here is the stock photo until I get another one.
  11. My very brief and unscientific testing on the way to work this morning has led me to believe that Sport Mode may also reduce DFM shutting down cylinders. Driving on fairly flat highway at constant speed and switching from Tour to Sport, the instant MPG dropped when going into Sport. Couldn't feel any downshift and I didn't think to look at the RPMs as I was coming up on traffic, so more testing is needed... I have the GM performance exhaust, and it 'seems' like it is louder in Sport, which could be the engine running on more cylinders more of the time, but again, more testing needed.
  12. I have no problem seeing my HUD with polarized glasses. Seems GMC addressed that by making them bigger and brighter. Same sunglasses on my wife's '16 Yukon, it is much harder to see.
  13. While I don't plan to lift my AT4, for GMC's, the AT4 is the only way to get body colored bumpers and door handles. There are several other things that are included with the AT4, and a couple that are not available unless you get the Denali package. - Spray in bed liner included - All weather floor mats included - Hill Descent control included - Skid plates included - Front bucket seats and center console included - Heated second row seats included - Body color bumpers and door handles - not available on any other trim package - HUD not available on SLT - Rear Camera mirror not available on SLT - HD SurroundVision not available on SLT You also get the red tow hooks, which are scientifically proven to be faster than any other color.
  14. Try this - not sure if it will work for idling, but it does work for disabling the auto-stop. If you pop the hood, start the vehicle, and then close the hood, it disables to the auto-stop. Might work to keep it idling while parked as well. I think it is a disable to keep the engine running during service, so it could disable the shut down during extended idling as well.
  15. The AutoStop eliminator video shows them removing and replacing everything in the center stack.
