Which factory stereo system do I have?
I have a 2003 GT and I am wanting to upgrade the head unit, but I am not sure if the stereo is the Mach 460 or the non Mach system. It currently has an aftermarket HU that was in the car when I bought it. Is there an easy way to determine which stereo I have? I know it's not the Mach 1000 because it doesn't have the subs or amp rack in the trunk.
