Phone kit mute on aura HU

[barryg]

Hi
Anybody out there know if there is a pin on th back of the mk1 leon aura HU to mute the radio when on a call. Im installing a se phone kit, which has a mute wire. I know the VW radios have a mute connection but as there is no diagram on the aura radio I dont know what all the spare pins do...
Any help greatly appreciated...

i think it is the bottom left pin looking at the rear of the radio. there is no wire connected to it in the harnes.. But when i connect the mute wire (from the car kit) to it the radio goes into phone mode (mute). The problem is, its doing the exact opposite of normal operation. I.e. when on a call the radio is in normal mode, and when off a call the radio is muted in phone mode????????????
Is there a + or - mute on the radio ???
