No matter what volume my IPhone is when in the truck and connected to Bluetooth, the truck speakers will ring at whatever volume it is set at on the radio, the radio has 2 different volume settings, one for radio, one for phone and I'm pretty sure Navigation is another setting, when a call comes in you turn your volume knob on the radio and the ringer will get louder, it should stay at the last setting every time you get in the truck. I guess thats where my confusion was, I've always had the truck ring when I get a phone call, never paid attention the ringer on the phone itself.

The calls are missed when you leave the truck.  The phone volume can be wide open when you get in the truck and will automatically go to zero when it connects to bluetooth.  When you get out of the tr

I'm having the same issue. I Just upgraded to IOS 12.2 Last night and this morning in my truck, it did the same thing again. So the last 2 versions of IOS has now dropped down to 2 bars on my volume.

I’ve been noticing these issues on my new trail boss but after receiving calls from people while driving I’m realizing it’s not ringing in the truck.  

 

I have the same issue with the ringer on my iPhone turning down when connecting to the truck as everyone else.  But today I realized my phone isn’t ringing when I get a call.  Has anyone had this same issue?  I’ve turned the truck ringtone volume up to max and I’ve even turned my phone ringtone back up to max and called myself several times with no ringtone.  It just shows the call coming in on the infotainment screen.  Anyone have any ideas to try?  I could live with my ringer being turned down but if I’m not looking at the screen in the truck I will miss calls as well.  Hopefully they get this fixed very soon.

So I found a work around that I found in another page on here by searching google. Not sure if everyone knows about it but it worked for me.  If you go into iPhone settings, then sounds and haptics, then disable “change with buttons”.  This is right under the ringer volume slider.  I disabled this and now the truck doesn’t turn my ringtone volume down every time it connects to Bluetooth.

I have tried this but it didn't fix my problem.  I will definitely try again!

 

One problem I was having is that the ringer volume in the truck was low and I would not hear it ring but just see it on the display.  I found a way to help this but I don't know if it is a long term fix yet.  What I did was have someone call my cell phone when connected to the truck with bluetooth.  While the phone is ringing, before I answer it, I was able to turn the volume knob on the radio and turn the ringer volume up in the truck.  Someone had said that there were different volume settings for the music and ringer volume.  But I could not find a way to adjust the ringer volume other than this.   Once I get out of the truck though, the ringer volume on the phone resets to the current volume setting on the truck audio.  I am still checking the ringer volume on my iphone and seeing how it changes based on the audio volume level in the truck.

I will be giving this a try tomorrow for sure- it has been driving me nuts!

I have a 2019 Sierra Denali and just recently purchased a new iPhone 11. Every time my phone connects with the truck it turns the volume all the way down. I have tried to turn it back up but it doesn't stay, goes down to silent. Incredibly annoying! Now my phone won't even ring through the truck speakers, even more annoying. Technology is good but come on fix the simple problems.

It's on the Apple forums to. People are saying it happens to them when they connect BT headphones. That tells me it's an Apple issue.

Yes.

When your phone connects via Bluetooth, you adjust the phone ringtone volume with the trucks volume controls. As your phone is ringing in the truck, turn the volume up to your desired level. Once that setting is set, it will stay at that level every time to connect to the vehicle. Your phone will still show that the volume is low but the truck ringtone will be at the level you set it at.

I keep my iPhone on silent mode all the time but as soon as it connects to the truck, my normal ringtone will play through the trucks speakers at the volume I set with the trucks volume controls.

That doesn’t fix the phone’s ringer volume dropping every time it hooks up to the truck. 

 

Meaning what? The ringer volume on the phone or the ringer volume of the truck?

 

Once the phone is connected to the truck, the truck becomes the master volume control and the phone’s volume buttons no longer matter. And once the ring volume on the truck is adjusted accordingly, there is no longer an issue.

 

Yes, the phone volume still shows that it’s low, but what difference does it make when the volume in the truck (the one that matters) is at the desired level?

The problem that most people have is that the phones actual ringer volume is set very low and remains so even after you get out of the vehicle.

      By newdude · Posted

      Based on what I can tell, yes.   As for updating it, its a mixed bag.  Updates do fix a lot of issues, but occasionally can create some oddities.  They do more good than harm though overall.     Here's what the most current one does and a  V171 Improvements Important: Improvements will vary by model, build configuration, system, and sales region. Not all vehicles have all features. OnStar and Wi-Fi may not work after remote start CarPlay may not automatically reconnect Part of the Driver Attention messaging screen may be in English even though the language is set to something else XM may not work After a dead 12V the radio may set to Arabic at each startup Bluetooth contacts might not be able to sync with the vehicle During an OTA the 12V battery may drain Customer might see a screen telling them to return to the dealer After changing the Wi-Fi SSID or password a device may not disconnect If a device is connected on the 2.4Ghz band, nothing will connect to the 5Ghz one, which could show as slow Wi-Fi speeds Customers might have noticed Wi-Fi dropping in certain areas and reconnecting later Customer might see the top of the screen blinking during Android Auto Android Auto may not connect CarPlay audio might momentarily cut out The "Add Phone" button may be grayed out The radio may not start up   V167 Most Notable Improvements:   Outside Air Temperature is incorrect. -You may see a popup message for Engine Shift.

Trailer Tire Pressure sensors may not be learned in the Trailer app. Not being able to return to the home screen while in the Camera app. After an ignition cycle, the radio might go to a black screen or stop working if using Sirius XM.

      Front End Rattle

      By AndrewF · Posted

      Looking for help troubleshooting a metallic like front end rattle. Figured I’d see if anyone had thoughts before I schedule an appointment with the dealer.   The rattle is fairly loud and occurs primarily when the front driver side wheel hits a bump, even fairly minor road seams. Sometimes does it when the passenger hits a bump but I don’t believe when the rear hits. Rattle still occurs when foot is pressing brake peddle so I think that rules out the caliper rattle I’ve read about. I’ve also checked the running boards and they are tight.   Most noticeable at slow speeds.    Any insight is appreciated.

      What did you do to your "other" car (aka musclecar) today

      We try to make cruise the coast. It’s where our favorite casino is. I only want to spectate. Never took a car. Always had one to take. I belonged to a club once. Even when I used to drag raced. It was during test and tune. Probably because I’m not a night owl, party person.

      Good looking Olds, and TRX!   I haven't been into car shows either. I'm probably not a convert but I did push myself this year to attend a few select events to challenge some assumptions and try to experience car-based social clubs in a different way. I joined up with the local Hagerty group for some cars/coffee events, group drives. A month ago I showed my '94 Camaro I rescued last fall at Radwood. Had a good time, but, there was some sitting around with the car and that's the part of shows I don't enjoy as much. I prefer to be a spectator, walk the show, grab a burger, go home.   Radwood was the only era-limited event, but where it had strict model year limitations, it made it up in variety. Having Jason Camissa there was also a hoot.   Where I see old 50's car shows, doo-wop and winga dinga music stuff fading out, same with "only" vintage muscle clubs, it seems to be the activity-based clubs/events which are gaining strong popularity. Places where all cars and interests come together.
