W211 - E320 - Phone microphone not working

[grahamwoodward]

I have a W211 E-class (2004) with Comand (Sat Nav, Phone, CD Multi etc) and a Nokia 6310i phone fitted in a MB cradle in the front armrest. It worked perfectly until recently. The phone dials out and I can hear the person I have rung but they can't hear me. They get interference instead. The phone works OK when out of the car. Anyone any idea why the mic isn't working?

Do clean the contacts on the bottom of the 6310i. The mic is in the mirror housing.

W211 E320 Phone microphone not working

Thanks TV, but that didn't change it. Out of the cradle the phone works. In the cradle I can hear the caller but they can't hear me. The US manual I downloded says you can mute the mic but the button on mine is greyed out. Looks like I may have to buy a bluetooth adapter!

W211 Phone problem - micro not working UPDATE

I went to Comand Online in Surrey last week - the problem with microphone not working was a faulty phone module in the boot. They fitted a secondhand unit for £200 instead of £500 new, and all is now OK. Thanks TV for your help.
