I am interested in getting a Mazda 6 sports wagon, but one thing i noticed is that there is no defining lines around the stereo to indicate a kit. I have tried searching at scoche and American International but neither of those companies have a kit. I also work at best buy as a mobile installer and none of the stores around me have worked on one yet. Already having a 7 in touch screen my intentions are to add navigation to it. But if i can't change out the stereo i would not be able to use my screen. Does anyone know what you can do about his except bite the bullet?
