Plan to upgrade radio for Mazda 6
Hey, my friends, I am planing to upgrade the radio of my Mazda 6 to a touch screen stereo dvd gps navigation with mirror link head unit and I found the seicane S301131 online which seems to work perfect for my car. I have never done this before, anything I need to aware before I do this? I want to make sure not to get other new problem before I start to do this. Thanks a lot.
