Bluetooth microphone stopped working - iphone 5s
 

I'm not sure if my bluetooth microphone has failed, or if the iphone 5s causes a problem where I can hear the person on the other end of the call perfectly, but they cannot hear anything I say. This happened immediately after getting the iphone 5s. I haven't tried pairing another type of phone to isolate the problem because I don't have another one handy.

I've searched the forums to see if there are known problems, as I've noticed the iphone 5s has different options on the MMI screen (microphone on / off as opposed to Mute On, which is no longer available - also, cannot synch phone book to memory, etc.)

I have rebooted the MMI, and this is for a 2006 A8L D3
SW: D3-HU 46.1.0 0805
HW: D3-HU 6346D2.0
FC SW: 06231AFC6AB320050
FC PS: 0050 FC HW: H01

I seem to be in a permanent muted state - any ideas? Is it definitely a failed microphone that coincidentally died when I upgraded to the iphone 5s - I had no problems with previous iPhone versions.
Thanks

Try it with another, older phone. Those geniuses from Apple are doing everything to make our lives complicated. No wonder that Samsung is taking over.

Try un-pairing and re-pairing with MMI.
I noticed in iOS 7 that the phone asks if you want to allow transfers sometimes.

Also the audio source had to be selected the first couple times I used the iPhone 5s then it seemed to stabilize, at least for me.

Additionally clearing all recents seems to help in many cases.

That definitely helps with all phones contacts list. MMI memory is smaller than a new phones one so if there is more to transfer then it can take it just not transfer anything.
