iPhone 5 and Mercedes Bluetooth issues

Thank you for your help. I too after many hours have been trying to pair my iphone 5 to my MB V3 Cradle. I follow you instructions but I get an error message to "confirm the cradle is turned on or within range." The light on the cradle blinks as per the instructions and I am sitting right next to it, any suggestions?

I am having problems with a lack of audio thru my handsfree when my iPhone 5s tries to either receive or make a call in my 2012 Mercedes E350. The phone is paired properly, I can see my phone name and the contact directory. The radio mutes properly when it attempts to receive or make a call but I cannot hear anything and the other party cannot hear me. The received and transmitted volumes are set per the MB instructions but still no luck. The audio source is set to the MB bluetooth connection on the phone. I can hear the other party thru the iPhone speaker if I select that mode but if I go back to MB bluetooth option, I hear nothing. Bluetooth connectivity and playback works for music. Very frustrating. Running the latest OS update on the phone. I have tried turning the radio off and on with the phone in the car and I have "rebooted the phone in the car with the radio turned on. Each time, it recognizes the phone but still hear nothing. Any suggestions?

HI all,

I have a 2014 GLK220CDI and iPhone 5s with iOS 7. Pairing is ok, but the quality of the sound when I speak over the car's bluetooth mic is awful, the person with whom I speak cannot hear what I am saying.

Anybody had the same problem and can suggest a fix?

thanks.
