Mazda makes a variety of factory installed stereo systems available as options for those purchasing a Mazda 6. For those who wish to replace a malfunctioning stock stereo or owners who desire more power and capability, you can choose from scores of aftermarket head units to install into your vehicle. Remove the factory head unit and disconnect it from the Mazda's stereo wiring and antenna cable. You can have the new unit professionally installed, or you can obtain the necessary adaptors and install it yourself.
