Parrot Bluetooth Kit

Have any of you guys installed a parrot 9200i bluetooth unit? I am planning on getting one for the van because it will play stuff off my iphone and has dual microphones and background noise cancelling tech in it. Essential in a van. I had a Sony bluetooth head unit in the Red beast and it was useless for calls when driving. Too much background noise. I am hoping the Parrot kit will do the job.

What I want to know is if you can install it with a unit that doesn’t have a telephone mute wire. If so how do you mute the headunit?

my mate has one that he has had in his last 2 cars. it was his brother (DIY si) that fitted it for him and i’ll see him tonight.
i’ll ask him over a pint and get back to you. unless anyone else has any answers.
cheers
