Ever since the iPhone iOS 14 update last week, the Bluetooth in my GLC is not working. It connects, but when I play audio on the phone, the car shows the device as being paused even when it’s playing. When I try to switch the audio to the car from the phone, it spins for a moment but won’t start playing from the car. When I make phone calls, the audio won’t come out of the car only from the phone. I can dial from the car, but the sound will only work through the phone. The only thing I have found that fixes it is rebooting the phone every time I get in the car. It’s a 2018 car and a 2019 phone. Everything was working fine before the update. Does anyone else have this problem? Does anybody have any ideas?

Thanks

Working fine for me. Have you tried repairing the phone and doing a restart? Now running 14.0.1.

Senatov

Restarting is the only thing that works, but I can’t reboot the phone every time I get in the car. I’ve tried unpairing and repairing it several times, resetting network settings, but I can’t find a permanent fix. This is annoying because the COMAND unit/MBUX system is something the dealer usually never is able to fix.

No such issues here, been running iOS since beta 1. Works fine on 14.0.1 atm.

Try toggling off & on Bluetooth using Multimedia system:Activating/deactivating Bluetooth®

Multimedia system:

Settings - System

Wi-Fi & Bluetooth

Switch Bluetooth on or off.

I ran into some issues as well--check the thread out, below...

Update: I had the car in for service at the dealership and just picked it up. They said there was an update for the head unit as well as the maps/GPS. It seems like phone calls now work over Bluetooth, but playing music is still not working. The only thing I have found that fixes it is rebooting the phone every time you connect to the car, which is obviously a disaster and you shouldn't have to do that. I'm afraid that this won't be fixed because it's one of those internal technical things between Apple and Mercedes that everybody points fingers on and nobody is able to fix because it has to come in software from Mercedes directly. They also told me that Apple is supposedly working on an update to come out later this year to fix it, and that MB and Apple have been in communication about it.

What are you driving? Your profile says 2020 GLE, which uses a different system.

Senatov

Just tried that and it didn't work unfortunately.

Also toggle off bluetooh and restart your phone.

Senatov

Restarting the phone is the only thing that works, but you have to do it every time you get in the car, which really isn't a solution. I wonder why that fixes it temporarily though, and how to make it last.

Really sounds like a pairing issue. Worth a call to MBUSA if you are in the states.

Senatov

I just called MBUSA and they acted like I was talking about trying to fly a magic carpet, and that the dealership should be fixing it. I told them this is one of those annoying tech issues where the phone company blames the car company and vice versa, and everybody's working off some bulletin notes and points the finger at each other. They said some executive team would call me back. Gotta love corporate America. I feel like Mercedes makes such nice cars but MBUSA totally ruins it from a corporate perspective. mbrace and that whole connected thing has always sucked.

I feel confident you'll get a call from exec/IT team and they will help you resolve the issues. Keep us informed & best of luck.

I would un-pair the phone through Settings>Bluetooth and then I would also go in and change the name of your phone by going into Settings>General>About>Name and also make sure you remove the pairing record on the MBUX side of things as well. Once you have done all these steps I would re-pair the phone and see if that resolves the issue. I used to work in engineering for Apple and bluetooth issues always came with new software updates and one year Chevrolet vehicles had a huge issue that was resolved after three to four months. A lot of times people will have a phone and then they get a new phone and restore a backup from the phone, which brings all the settings and name of the phone back. You can tell this happens because sometimes when we looked at logs an iPhone X was named John's iPhone 6s, but the point is that the head unit sees the name of the device and then also the bluetooth address and sometimes the same name with a different bluetooth address can cause connectivity issues. If this doesn't work I would contacting Apple and asking to have an RTA filed with engineering, which will collect logs and provide a fix.

Wxchaser

Sound advice!

Senatov

Didn’t work unfortunately. What is an RTA and how would one file that for this issue? Thanks.

GLK63AMG

You will want to call Apple support number no it’s called a request for technical assistance. You will get transferred to the right department.

Senatov

Just to update this for anybody else having the issue...I took it to my MB dealer, they updated it which fixed the phone, but media over Bluetooth still doesn't work. I called MB USA and it took them a few weeks, but they got in touch with somebody high up in engineering internally and then I heard back from MB USA customer service and they said they are aware of it and there will be an update for the car out before the end of this year. I also called Apple as GLK63AMG said and they actually did exactly what he said and had me install a profile and run through it while it wasn't working which sent them back data which apparently is going to allow them to fix it on their end. Hopefully they weren't making stuff up and one of them fixes it soon.

GLK63AMG

Sounds good. They most likely will come back and say the issue is under investigation and to keep your software updated. The good thing is Apple is not afraid and has the ability to continually release updates. Last year I had a problem with my Bluetooth in the car and Hey Siri. I reported around October and they resolved in first half of December.

Senatov

Just an update...I updated my phone to iOS 14.1 and it’s still not working, but I noticed it will randomly start working very rarely every now and then. I’m getting the 11 Pro Max in a few weeks so I wonder if that might fix it by chance.

Wxchaser

I have an 11 Pro Max and it has worked impeccably. Now convincing me to upgrade???

Senatov

What model year is your GLC? Do you have the COMAND/multimedia system? We have the same phone, I'm curious if we have the same car. What iOS version is your phone on?

Thanks.

Wxchaser

2020 Mercedes-Benz GLC 300 4MATIC SUV/GLC300W4. No, I have MBUX multimedia system.. I have used iOS 14.0 and iOS 14.1 so far with no issues.

Senatov

Yeah I drove a 2020 GLC loaner while mine was in the shop for this and the MBUX didn't have the issue. It seems to affect the COMAND systems. I'm curious if there is someone out there with a pre-MBUX system and an iPhone 11 on iOS 14 where bluetooth audio WORKS.
