Mute connection in Swing unit?

Hello.

I would like to know if the Skoda Swing radio/cd unit has a mute connection, for connecting an aftermarket handsfree kit

with auto-mute ?

For example, in some radio/cd units, there is a single cable that can be connected, so that when you receive a call

the handsfree kit mutes the radio/cd.

Any info on the Swing unit?

I'm still waiting for my 1.2 TSI Elegance (with Swing, not Bolero) to come, but wondering if it has external mute.

Thanks in advance!
