Radio won't mute !!

Hi everyone.
I've just retro fitted a bluetooth system to a 02 X5 4.6is from bimmernav with no problems at all.
The only issue I have is the radio does not mute when a call is made or recieved although mutes fine with nav.
Does anyone know how to resolve this?
Thanks
Jonny

Measure the voltage on the line when a call is active.

TELM is on pin 8 of the X322 loom connector
It's white with a brown stripe
Goes to pin 10 of the X18126 of the radio module (old gen)

Thanks for that I will try it & be sure to let you know the result.
Thanks again

Can't find any evidence that the telm is not connected. Although I am totally novice to these things
Thanks anyway
