In the last couple of days I have started having an issue with the Columbus System and my phone (HTC Desire).

The phone pairs ok and I can use it to dial numbers, receive calls etc but the issue is that when a call is answered the audio does not come through the speakers in the car but reverts back to the phone itself - what is very strange is that the radio remains muted until the call is ended.

I have tried the usual phone reboot, re pairing the devices, setting the Phone Settings on the Columbus back to factory default - all with no joy.

This just started happening all of a sudden and I have no idea why - any help or pointers would be appreciated.

Note : I have had the HTC for a number of months and it operated fine with the audio coming through the car speakers as expected.

Thanks

I spotted a setting somewhere in the phone menu for private call. My guess is this does exactly what you are seeing. Puts the radio into mute but leaves the phone audio with the phone. Check that setting hasn't changed. I guess it must have been in the MFD menu for the phone.
