I wanted to know if anyone here knows if you can have a Mazda dealer add the navigation system to your car and get Bluetooth with it. I called the dealer I got my car from but I don't think they understood what I want to do. I want to get Bluetooth in my car since you cant get it on a sport manual. I can go out and get a nice one at Best Buy but if I have the dealer do it I would not be voiding any warranties. Thanks and Zoom Zoom
