  1. So it seems there is conflicting info in the 21 sierra manual. 2021 Sierra manual has a several pages of instructions for programming keys but for FOB it says: Programming Transmitters to the Vehicle Only RKE transmitters programmed to this vehicle will work. If a transmitter is lost or stolen, a replacement can be purchased and programmed through your dealer. Each vehicle can have up to eight transmitters programmed to it. See your dealer for transmitter programming. BUT... A few pages later in the manual they give instructions for programming additional ones if 'two recognized transmitters' are available, and another set of instructions for if 'two recognized transmitters' are not available.
  2. iirc, the manual has instructions for key programming, but says a dealer has to do the fob programming.
  3. Or they are 'allocating' that feature, and the dealer doesn't currently have allocation.
  4. 2020 truck audio rpo descriptions don't include wireless wording, since it the feature was added in 2021. Truck order guides don't show IOU (which also doesn't show 'wireless')
  5. IOR can be 8", according to the order guide. 7' seems to be in lower trims, 8" higher trims (which also seem to usually have upgrade option) From the order guide: IOR Audio system, GMC Infotainment System with 7" diagonal color touch-screen, AM/FM stereo with seek-and-scan and digital clock, includes Bluetooth streaming audio for music and select phones; featuring wired Android Auto and Apple CarPlay capability for compatible phones IOR Audio system, GMC Infotainment System with 8" diagonal color touch-screen, AM/FM stereo with seek-and-scan and digital clock, includes Bluetooth streaming audio for music and select phones; featuring wired Android Auto and Apple CarPlay capability for compatible phones IOS Audio system, Premium GMC Infotainment System with 8" diagonal color touch-screen, includes multi-touch display, AM/FM stereo, Bluetooth streaming audio for music and most phones; featuring wireless Android Auto and Apple CarPlay capability for compatible phones, advanced voice recognition, in-vehicle apps, personalized profiles for infotainment and vehicle settings IOT Audio system, Premium GMC Infotainment System with Navigation and 8" diagonal color touch-screen, includes multi-touch display, AM/FM stereo, Bluetooth streaming audio for music and most phones; featuring wireless Android Auto and Apple CarPlay capability for compatible phones, advanced voice recognition, in-vehicle apps, personalized profiles for infotainment and vehicle settings. Includes greater memory.
  6. Wireless AA/CP availability also depends on which 2021 audio is ordered -- and of course the phone must also support it (my truck can do wireless, my phone does not...) 7" IOR and 8" IOR audio have wired AA/CP capability IOS and IOT audio have AA/CP wireless (and wired) capability
  7. Fwiw, the 'diesel off-road package' (which is the only way to order LM2/10spd and 3.73's) is only available on some LT and RST versions, and is not available with max tow package. So far, the package is only offered on the chev.
  8. The locations need to be re-taught. You can buy a re-learn tool or visit you friendly dealer. It is no longer possible to teach the locations by adjusting tire pressures the way it was done in the past. (even though the trailer tire sensors can still be done that way). Dealer near me keeps one of the teach tools in service reception and will do the 20 second walk around anytime, no charge, without an appointment.
  9. You might find the overall tire diameters of the tire sizes GM offers are closer than you think. https://tiresize.com/calculator/ For 2021 Sierra, NHT is only offered on SLE, the 3SB version of the Elevation and the SLT. NHT requires either the 5.3 or 6.2, Of those 3, the 6.2 is only available on SLT. Requires 18's or 20's. Note available with X31 or 22's. Looks like there may be some restrictions on ordering NHT for 'stock' orders as opposed to 'sold' orders. On the chev, NHT is available on Custom, LT, RST, LTZ and HC. (also has lots of restrictions) Tow mirrors are now available without NHT, and NHT doesn't include them.
  10. Doing mostly 2 lane rural driving, this one is regening about every 250 - 300 miles. I was always able to notice when regens occurred on the LML and L5P trucks I ran for many years - but not on the 3.0L. Decided to add an aftermarket monitor. It show regens about every 250 - 300 miles, and that they only last about 10 or 12 minutes/miles. I've never put any additive in any of them.
  11. https://tiresize.com/pressure-calculator/ It's about tire pressures, but includes info on differences in load range, load index and max pressure ratings. May or may not be useful to the discussion.
  12. More thermostat infor, for your reading pleasure. Thermostat is not an on/off device. https://www.stant.com/index.php/english/products/consumer-products/thermostats/abcs-thermostats/ From the stant link: THERMOSTAT TEMPERATURES Thermostats have a “rated” temperature such as 180F or 195F This is the temperature the thermostat will start to open, give or take 3 degrees The thermostat fully open about 15-20 degrees above its rated temperature Many thermostats have a “jiggle pin” or “check valve” that allows trapped air in the cooling system to pass through the thermostat and be released from the system. If a Stant thermostat does not have a jiggle pin, it will have a "bleed notch” or other method of removing air from the system.
