I just picked up a Sony T637 phone with Bluetooth (a fantastic phone on the Cingular network). I'd like to have a Bluetooth handsfree kit installed in my Touareg/Nav. I'd like a kit that automatically mutes the audio system for calls and feeds the phone audio through the audio system's speakers. I don't have OnStar so the phone and aux inputs are free. Has anyone installed a Bluetooth kit? Recomendations on specific kits and/or installers here in Connecticut? Thanks.
