If you call Parrot they will tell you that the Parrot is not compatible with the Nissan Bose amp and you must use an external speaker. I just installed a much better solution. This box mutes the radio and matches the Parrot audio to the Bose amp so your caller comes out of all Bose speakers. It sounds fabulous and installs in less than an hour. No wires to cut - plug and play. If anyone is interested,
