Tried searching for similar issues but to no avail,

just took home a new C300 that i'm loving but I'm having some major bluetooth connectivity issues with my iPhone 6(AT&T).

The issues seem to happen randomly (sometime's it works flawless, other times not) but the phone constantly connects/disconnects from command during calls(on the command screen it flashes "CALL ENDED") while the call is still ongoing (just can't hear it via the command system).

I've also noticed that if I try to stream music or make a call within the first minute of the car being on, that it sometime's results on the whole system making no noise [stereo, navigation etc.] . Its almost as if I trigger SIRI but its stuck indefinitely.

Lastly, I've noticed some major issues with it picking up on calls that are in progress when I start the call (something that happens frequently to me).

Anyone else have any ideas/tips? It's been a huge problem for me in this first week of owning the car.
 
Two months ago I took delivery of my new AMG C63. Intially my iPhone 6 Plus worked very well. After two weeks it acted like yours.

Navigate down to the cars screen into the Bluetooth pairing setup, remove your phone, reset it (the car) to its original defaults as it came from the dealer. Then start from scratch and pair your phone. Once that's done with mine has worked flawlessly
 
I have seen multiple threads on here and on Apple forum about bluetooth problems with many different cars since IOS 8 was first launched. In fact Apple even issued a note about deleting and re-adding the bluetooth device in an attempt to deal with this problem. From what I have seen it works for some and not for others.

This is what you get if you do a simple Google search.

awesome,
I'll give this a try. I imagine it wipes clean ALL settings? shame.
 
Funny I have the same issue with my Gla 250. My wife's phone stays connect but my 6plus is random. I've given up on it.
 
For my 2010 ML350, I have 2 Bluetooth connections...one for phone calls and one for music. They are separate and distinct devices in the iPhone 6 Bluetooth setup. When I try to connect to both, it works, but phone calls become flaky and drop.

I've disabled the music Bluetooth connection and only use the phone call Bluetooth connection. For music, I use a hardwired connection. With this setup, all is well.

I had the same issues with my previous iPhone 5s.

And I tried resetting the MB Bluetooth setup and starting over...made no difference.

God, this reminds me of Honda/Acura's current setup. Just terrible design. Why can't they be "one device?"

All the new two-screened Honda/Acura cars have this issue with all my phones. You set it up as an audio device and then as a phone in separate menus. Now, next time you get into the car, it MIGHT connect both, one, or none of them. Completely random and never works right.
 
I have the same issues in my '12 Jetta that I bought recently. Deleting the pairing and repairing it only helps initially then the problems come back.

The issues with me is that the bluetooth will work but I can't change the song, stop, or play it from my touch screen or steering wheel controls. It'll just be grayed out. It's pretty random when it wants to work or not. And when it works properly I can control everything.
 
Love how all the Benz owners go out their way to describe their car. My 2014 Audi A4 ( s line with the prestige package that includes Bluetooth and navi) has absolutely no connectivity issues

It's rather surprising that you fail to understand why it's important to describe year and model.

If you're having a problem with an iPhone, does it matter if it's an iPhone 4 or iPhone 6?

Mercedes telematics/audio/communication/navigation systems are known by the name "Comand". A well established line consisting of over ten major upgrades of hardware and software from year 2000 till the present, it matters what model and year your vehicle is.

Within a single model year there are variations in the system between different models like sedans, SUV, roadsters, etc. Further broken down depending on the engine you choose, V6 / V8 / V12.

Therefore a vehicle description is essential.

It's pretty important to have year/make/model/trim because they vary so much these days. Even with Audi... They didn't add A2DP support until the 3G+ MMI came out, which was sometime around late 2012-2013ish.

Pre 10/10 build date BMWs didn't have A2DP support and they lacked support for the "normal" Apple white cable. You had to use a special Y-cable.

For the 2010 ML350, the Bluetooth phone connection is built in to the COMAND unit. The Bluetooth music connection is via an optional MB device connected in the glovebox. It's still configured via COMAND, but it's separate. Hence the 2 separate Bluetooth connections.

I was surprised that having 2 Bluetooth connections on my iPhone5s/iPhone6 was even possible, but it was spec'd in recently.

Not sure who's at fault for the dropping phone calls when 2 Bluetooth connections are going at once...likely MB.
 
My 2009 s class works with iPhone 6 - however when I first got my iPhone 6 it did have connectivity issues - my 5s worked day one to it was sold without an issue

The issues my i6 had was when I would get in the car it wouldnt connect immediately as the 5s did. Not sure what changed but now it's perfect
