Do Not Sell My Personal Information

Recommended Posts


My partner has got a Ford Focus 2012 model. It has got the Sony radio. We are having trouble with the mic.It was working fine and all of a sudden the mic is not working. When you get a phone call it connects via bluetooth but the bottom Left on the screen says mic off? The bluetooth still works but nobody can hear you. You can highlight it but it doesn’t change anything. 

Today I fitted a new battery and was hoping this reset everything but it didn’t. I have taken one fuse out from under the glove box and removed 2 in the boot. But again this hasn’t worked and everything was still the same on the radio ( didn’t loose any saved stations)


Has anybody else had this issue?

This seems to be the basis of your issue, if the screen says, 'mic off', it simply won't work. You just need to find the setting to turn the mic back on again...

See if this advice is any help.

The Bluetooth/Voicecontrol module is connected to the same fuse as the radio. There are several ways to reset the Bluetooth/Voicecontrol module when it is not recognised by the radio (the radio will only mute when no module is connected or detected).

1. Remove the radio fuse for about 20 minutes.

2. Remove the positive battery lead for about 20 minutes.

3. Disconnect the Bluetooth/Voicecontrol module and reconnect it after 20 minutes.

4. Reset the module by a suitable diagnostic interface. An ELM327 interface combined with the free ELMconfig software has the ability to reset the module.

When a module is often not recognised this could be a sign that the module is defective. First you could try to update the firmware of the module. If the module supports USB you can do this yourself by performing the Ford Audio Update (which can be found online). If the module does not support USB it can only be done by a Ford dealer. If the firmware upgrade does not solve the problem the module can be considered defective. Unfortunately the Ford Bluetooth/Voicecontrol module is a relative weak part. These module become defective quite often.
