I have a 2016 Silverado 1500 crew cab with the I05 radio. Took it to the dealer for pairing issues and they replaced the HMI and updated firmware support from 3B020 to 4B012.  This solved the pairing issue that I was experiencing of having to repair the device every time I entered the vehicle.  Now I found that if I am on a call when entering the vehicle The call will go muted and I have to hang up and recall instead of the call transferring in the truck. (Even though it use to before the update.) Took it back to the dealer they seem to think after talking to the GMC engineer it is a software issue in the update that has disabled it. They have the same truck on the lot with an  I05 radio. They made sure the phone would transfer the call getting into the vehicle with no issues. Then they applied the updated software and same thing happened the calls will no longer transfer to the vehicle. Anyone know of a fix for this or a way to roll back the software as they say they are unable to load previous versions.

ANY HELP WOULD BE GREATLY APPRECIATED!

Sounds like the dealer is working with you at least.  You may have to wait until GM fixes the bug they introduced on the last update.  It sucks when developers do not properly test their software before checking in changes and having it released.  Keep pestering the dealer, they need to keep pestering whatever department is responsible for Bluetooth software releases.

Yes the dealership has been awesome it was the GMC engineer that was horrible, saying that they couldn't revert back to the old software and since it doesn't state in the owners manual that it should transfer when entering the vehicle then its not their problem.  And yes he did say it as I was standing there when the phone call was made!

You may want to look into what the exact wording is in the manual, then look at what the standards are that they are claiming to meet.  If they claim to meet a standard, then it does not matter if it doesn't specifically state that they support auto-handoff of a in-progress call.  Sorry I can't be more informative about this, I am just going on a gut reaction to what they said.  With the advent of Six Sigma crap, they need to really follow whatever standards they claim to meet.  They have documented whatever features they want in their software before developers create it.  Simply saying it is not in the manual does not preclude them from actually following the feature list provided during development.  I can guarantee there are features that are not documented in the manual, that does not mean those features do not have to work.  I believe the term is "easter eggs".

Yes that was my argument. Just because it doesn't say the door opens doesn't mean it isn't expected to open.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By newdude · Posted

      No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.

      Active Grille Delete

      Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.

      I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?

      Tire pressure for 37s

      By PBNB · Posted

      Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter
