Just picked up an AT4 this weekend and have been working through the learning process on the various "systems" on this new generation. One thing I've noticed and was wondering if anyone had experienced and if so how it might be resolved is when an iPhone is connected via bluetooth it seems the infotainment system changes the ringer volume on the iPhone. At first I though I might have turned it down but I've verified it a couple of times by starting the truck, having bluetooth connect then shut the truck off, get out and check my ringer volume. Sure enough it drops down to the last two or three bars on indicator on the iPhone. The other thing I noticed is that when you have it connected via BT and have the music app open, when you change the volume in the truck the volume indicator on the phone goes up and down. I never had this issue with my 14 or 16 All Terrains and if in-fact I'm not crazy I believe this is going to be a bit problematic for folks who experience the same and end up missing phone calls, texts and emails (at least the ones who rely on an audible indication from their phones). Anyone else seeing the same?

I noticed that also.   I have to double check but I did see somethong in the manual that this happens.

I believe I might have figured out a work around on this. I disabled the "Change with Buttons" option on the iPhone under Settings-Sounds & Haptics and tested it and the ringer volume remained where I had set it.

I have the same issue. It must be a bug between the iPhone IOS and the chevy system. I will try the disable you were talking about. I also noticed that when calls came in I could hardly hear them on the chevy system when bluetoothed in. I turned the volume up on the truck and still it was not enough. Then I raised the volume on my phone via those side buttons and it was super loud. Hopefully disabling those button will fix that issue too.

I noticed this too and it’s been bothering me, I just checked my phone and I already had that disabled but have been experiencing it. [emoji20] min is a Silverado but I doubt it’s much different.

I disabled the “Change with buttons” as noted and it  no longer changes the ringer.  Iphone7 if that makes a difference.

I just bought a new Chevy Blazer RS and am having the same trouble with the volume on my phone.  Two different techs worked for a couple hours to resolve the problem and there is no resolving the problem.  No matter what is turned on or off, it stills lowers my volume down to bare minimum.  The techs have never seen a problem like this and were baffled.  They said I should go into the Apple store and explain the situation to them and see if they have heard of or found a solution to this problem.  Going tomorrow to Apple. 

I have an Iphone 6S plus.  I will update once I go into the Apple store.

Mine does this with my iPhone XS. Ironically, the Ford I had before this would do the opposite. It always maxed the volume. [emoji1787][emoji1787]

Mine does the same thing. I used the same workaround thinking it was actually something with my case. Glad to know i hadn’t lost my mind.

I have a 2020 2500 and this work around is not working. I go to two ticks on the volume for my iphone Xr every time it connects to the truck. iPhone seems to be unaware of the issue. Anyone come up with any other solutions? I am continuously missing calls after driving.

We just picked up a 2020 GMC Terrain Denali 3 days ago. We have an iPhone 6s and an iPhone Xr. Both have Bluetooth volume issues when on in Terrain. Volume on car and iPhone is at max and it’s very low. Frustrating. Never had this issue 3 days ago with 2014 Buick Encore or 2016 Chevrolet Equinox. We think it’s the 2020 GMC Terrain, not the iPhones.

Also have the same issue on my 2020 AT4 HD. iPhone X volume goes down to two bars of volume, and phone calls when bluetooth connected are quiet with phone and truck volumes maxed. Then I call onstar for something else, and almost blew my ear drums

Using CarPlay is the only solution to this problem that I have found actually works. 

 

It's very annoying. 

 

Also, my system stopped allowing me to sync contacts from my iPhone about 6 weeks ago, totally at random. Can't get it to sync no matter how many times I delete / re-add the iPhone, etc. So frustrating. Worked fine for the first 4 months I owned the truck, then stopped out of the blue. Not due to a software update, either.

    • www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.
    • Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.         
    • I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far. 
    • I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install. 
    • Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
