  1. I tow two different boat trailers and I installed the TMPS sensors in the tires on both. The app works for both (except for the accuracy of mileage) giving me tire pressure and temperature. When towing one of them I had a blowout and lost the sensor. I have a new pair on order but I have a question about installing the new one. Will I be able to just go in and add the new sensor, or will I need to delete that trailer and start over?
  2. I have been meaning to experiment with this but haven't gotten around to it. Let us know how it works.
  3. It is my understanding that the honk will work without Onstar but in order to receive a notification on your phone you do need Onstar.
  4. I took another trip today. Hoping that the issue would disappear now that Onstar was no longer active I reset a trip log on the truck and the trailer mileage in the app to zero. I watched closely and they were in sync as I started the trip. After a while I got into some traffic and I needed to pay attention to driving. When I was out of that I checked the mileage and found that the trailer mileage was 20 miles less than the truck. I don’t know if it had just stopped tracking for a while or if it had pealed off 20 miles. I paid attention for the rest of the trip and it was tracking. When I got to the ramp it was still off by that same 20 miles. I then parked and turned the truck off while I got ready to launch the boat. When I started the truck I checked the mileage on the app. It had changed and showed 4 miles more than the truck. When I was driving home that 4 mile difference stayed the same for the whole trip, meaning it worked correctly. Since I only intended to use this for tracking maintenance needs I will just live with it. I will mention it to the dealer when I take the truck in for service but I doubt they will figure anything out.
  5. Well I don't know what is going on. I took another trip with the starting mileage at 49. This time the destination was 64 miles away. That means that when I got there the mileage should have been 113. The app said the mileage was 119. While that was off it wasn't the worst. When I got in the truck to go home the mileage had changed to 161. As I traveled the mileage ticked up and was at 210 when I got home. It should have said 177 (or 183 if you add 64 to 119.) Any theories? Nothing adds up on this trip.
  6. 2020 Denali 1500 with Ultimate Package. I had hooked up my trailer when I first got the TPMS sensors installed to ensure everything was working. I took it around the neighborhood and put 2 miles on it. Yesterday I did my first tow to a boat ramp that I have used many times. I know the mileage to that ramp is 23 miles each way, or 46 miles roundtrip. When I started the trip I was watching the app and everything was working fine. When I got to the destination I stopped paying attention to the app and focused on the task at hand. When I got back in the truck to head home I was shocked to see the miles on the trailer displayed as 48 miles. I left it on that screen and noticed that the mileage moved up and down during the drive and settled at 48 miles which would be correct for the trip I took plus the first two test miles. It is as if the app was estimating the roundtrip. Is this possible? While I have that ramp loaded in the navigation system as a favorite and home as a favorite I did not have it turned on for this trip. I'll pay even more attention to it on the next trip but I was wondering if anyone else has noticed something similar?
  7. At first I didn't want to use those holes so I didn't have an obstruction on the floor, but after thinking about it if that is ever a problem I can just remove them temporarily. Is there a reason you went to the trouble of reducing the tube to fit in the existing holes instead of drilling them out to accept the 1/2" tube?
  8. I was hoping to get an accurate reading before pulling out of the garage in case the tires need to be topped off. That means I'll still need to check them with the gauge. I think what I will do is lower the pressure in one tire by about 5 lbs and go for a drive to see how long it actually takes to update.
  9. I got the sensors installed on my single axle trailer and hooked it up to the truck. I had already attached the trailer before and saved a profile so all I had to do was learn the sensors. I don't have a tool so I had to do the pressure change routine. With the truck running I entered the program in the trailer app. and selected single axle. I had everything ready so I proceeded to let the air out of the first tire. I dropped it by 15 lbs (with a very accurate gauge) and never got the horn beep or lights flashing so I went and looked at the screen. The tire I had worked on had the green check beside it and it was counting down on the second tire. I went back to it and dropped the pressure 15 lbs, again never getting the horn or flashing lights. I went back to the truck and it said that tire had been learned also. Then I checked the pressure. The first tire listed the pressure at which I had started and the second tire had the pressure at the level I had dropped it to. I then turned the truck off and filled the tires to the proper pressure and when I started back up both tires listed the low pressure. I was going to try again but when I selected the setting for that it told me the sensors had already been learned. On a hunch I decided to drive around the block and within a short distance both tires were showing the correct pressure. Any ideas what is going on and more importantly can I trust these readings?
  10. I got the RetraxPro ordered and have been reading the installation instructions. Cover will be put on a 2020 Denali 1500 SB. The only question I have at this point regards the drain tubes. There are some plastic plugs at the front of the bed but I am sure that they are going to be too high to work correctly. Is that correct and if so is there anything that I need to be aware of before I start drilling holes?
  11. That is another reason I like to know the mileage under specific conditions. It lets you determine where you want focus - economy or speed.
  12. I understand that but I was asking about mileage on the highway at approx 60 mph, not the overall average. I like to know what the mileage is in specific conditions.
  13. I picked up my 2020 Denali 1500 last week and the first day I put about 100 miles on it driving back roads. Then I needed to drive about 300 highway miles and since I do like to follow the break-in procedures GM recommends I took it easy. I'm not going to say I kept it under 55 the whole time but I did not run it hard and I tried to vary the speed as much as possible. I am still on the first tank of gas so I can't calculate the mileage manually but the DIC is saying I am getting 24 to 25 mpg on those highway miles. Can that be right? I never expected the 6.2 to get anywhere near that.
  14. I got around to checking out the visor on the truck. It is a smooth finish that looks like it will be difficult to get off. They remind me of the ones that were on my Z4. Those HAD to come off as it was going to look horrible going down the road with the top down and the visors up. I had to use a solvent to melt them which also made the visor wavy. I then had to use a heat gun to melt the visor back smooth. I don't want to go through that again.
