Gotcha. thanks for the info!

Hi, Thanks for the reply. Bear with me but what is regen?

Hello again everyone, I have a question I have been wondering about for a while I wanted to run by you. While driving, my exhaust sometimes sounds a little different and I am not really sure why. This may not make sense but giving it a shot at explaining it but most of the time is the usual hum I have always heard from trucks but from time to time it is a much lower deeper purr kind of sound but a definite noticeable difference. This is my first diesel vehicle so maybe this is normal and I see no difference in actual performance but it always makes me wonder why this happens and only at certain times. For reference, I only have a little over 5000 miles on the truck. Thoughts?

Ok, thank you

Hi, how may numbers of the VIN do you need? Also, I didnt even think about any controls for light/dark, etc for the HUD. I don't see a specific button in the truck looking related to the HUD so I may just be out of luck sadly.

Hi, I have a 2021 Sierra with the Denali package and for some reason the HUD isnt an available option. I think the newer models of Denali have different levels of options but I thought the 2021 Denali was theoretically supposed to have most everything aside from the optional accessories but HUD is not an option on mine. From what I can tell, all the components are installed which makes me think it was simply disabled and sold as an additional option. Is there a workaround like reprogramming the ECU to turn this on by chance? Thanks

Thank you. I will try again

All, I have a dashcam in my truck but I don't want to run the USB power cable all throughout the truck and use the little stick-on cable connectors so I am looking for suggestions on how I can tap into the existing truck accessories that are powered and install a small USB cable I can connect the cam to... like maybe the rearview mirror power or something up toward the top of the windshield. Has anyone installed anything like this or have suggestions? Thanks

Hello everyone, Wanted to run one by you and see if anyone knows. I can't remember if it was my old Android phone or my new iPhone but when I would use the handsfree text through Intellilink it would tag the text with something like "Sent from my GMC Sierra" or something like that. It is no longer doing this. Is there a way to turn this on where it tags each text with this?

Hi Guys, I wanted to run one by you. I went to put some diesel in my truck a few days ago and when it started fueling I heard what sounded like a boiling sound and a small bit of what appeared to be steam came out of the hole where you put the nozzle in. It was brief but i have never experienced this before. I had been driving it to work about an hour but I kind of felt around the areas on the bottom I could reach and nothing seemed hot. Truck has about 850 Miles on it........Anyone seen this or have ideas?
