Bluetooth disconnect during a call : iOS7 on 5S

Having the same issue. with iPhone 5s and iOS7. Was working fine with my iPhone 5 and iOS6 - not sure if it is the new phone or updated iOS that is causing the issue. 2013 x5.

ray333, I have this same issue on my 2012 BMW and your proposed solution does not work for my i5s. In fact, I got another loaner BMW X1 (2013) and the same problem occurs, even with iOS 7.0.4 (released two days ago).

Another friend of mine has a 2012 BMW, i5s, and same problem. He even did a complete wipe and reinstall of the OS and still no luck.

Hope Apple is aware of this problem and is working on a fix!

I have the same problem on a 2013 X1 and iphone 5S .

Tried deleting a repairing with no luck. I'm not clear if it's an Apple issue or a BMW issue but I suspect the latter as I don't think I've had the same problem in my wife's car.

I updated the iDrive software in the X5 via the USB route and it seemed to get better, but then It dropped again yesterday. Very frustrating.

Still having issues and, based on my four visits to the Genius Bar, this is not on Apple's radar as far as I can tell. Let's keep posting on this discussion (and also in-store) so that Apple knows that this is a real issue, not a one-off fluke.

Posting here on the discussion board does not put this issue on Apple's radar. They do not participate in the forum. The way to get information to Apple is via the feedback page. www.apple.com/feedback and click on the appropriate link.

Not discounting your problem, but usually problems with Bluetooth connections to vehicles is on the vehicle side. Apple loads the latest Bluetooth profile and the phone and the vehicle's do not support it. Check with the vehicle manufacturer to see if it supports iOS 7 and the latest Bluetooth and see if they have any updates to the vehicle's Bluetooth firmware.

Yes, I did in fact update the BMW firmware to the latest, but that didn't solve the problem.

(Despite that, would recommend all BMW owners update their firmware: bmw.com/update)

Not sure why no problems with iPhone 5 running iOS 6, but big problems with iOS 7 on iPhone 5s. Isn't Bluetooth just a standard that all device makers must adhere to?

I wonder if there is a difference in the Bluetooth stack in iOS 7 that BMW needs to update their firmware to support??

Perplexed and frustrated!

That is usually it. Changing the Bluetooth when you update iOS is easy, as well as updating the new devices (5c, 5s). After that, it is up to the vehicle manufacturers to match it. Try this support document and see if anything there should help. http://support.apple.com/kb/TS3581

I'm surprised that forgetting the iPhone in the car system and forgetting the car in the phone system, then putting both devices back into discovery/pairing mode did not work. It usually does.

Bluetooth car and iPhone resetting didn't work, neither did the other recommended solution on that page, iPhone restore to factory.

Looks like either BMW or Apple, or both, need to fix something as this doesn't appear to be isolated.

A friend of mine suffering this same issue went to an especially generous Genius Bar over the weekend and they offered him a new i5s to see if it was something in the hardware...waiting to hear back from him if any improvement...

It seems to me that everything that I have read has had to do with a number of European cars and luxury cars, such as BMW, Mercedes, Audi. I'm not saying that is necessarily the problem, but once the phones are released and iOS are released, it is up to the vehicle and other accessory manufacturers to bring their devices into compliance with the phone software for them to work.

I feel fortunate, as my 2012 Hyundai has worked with my old 4s and the sofware it had on it, and when I purcased my 5s in October, it worked just find for it as well. No problems connecting, or maintaining connections. While it seems as though there are a lot of issues, it really isn't widespread. Good luck trying to find a solution.

Any reply from your friend yet? This is happening to my wife with her 2012 BMW X3 and iPhone 5s running iOS 7.0.4.

She just tried forgetting the phone and the car, rebooting both, and then re-pairing and it seems to have helped at least for the past 20 minutes. Fingers crossed!

No luck with the replacement iPhone 5s. Still drops the connection.

Looks like a bug/feature of iOS 7.

I think I'll go to BMW to get them to take some action, as well.

I have a 2011 740i. I have the same issue, and have tried:

1) replacing phone

2) restoring IOS7

3) updating BMW software (the most recent update handles IOS5 for bluetooth!!!! not up to speed !!!)

4) talked to my service rep

I am going to see if there is a way to communicate with BMW. I recommend everyone making sure they register their issue with the local dealer so it filters up into the mothership.

Ready for a Samsung.....

I have a BMW 528i (2012 model). I had no problem with my iPhone 4s with iOS 7. However, when I replaced my phone with a new iPhone 5s with iOS 7, the bluetooth cuts off from time to time during a call. The bluetooth disconnects and more often than not, it connects back again after a few seconds.

Forgetting the devices on the car and the phone does not help. An intereting observation I made is that streaming music to my car is very stable over bluetooth. I therefore assume that the bluetooth cuts off only during a call.
