I have som problem when i try to install a parrot mki9200 in my mmcs with navigation and amplifier, i have buy a mute adapter i have connected in the amplifier in rear of my car, and a extension to the front. My car radio do not get any message or mute down when i start bluetooth music or a bluetooth call, anyone here have a sulotion? Is it more that one mute vable behind my unit? Mu musin from bluetooth do not going through the amplifier, it is just connectet ti the speaker-wire? But it chould go througt the amp. The parrot domt turn of when i turn of the ignition and it still play music from bluetooth after the ognition is off.
