I have little to no knowledge on head units and radios. My 96 GT came with an aftermarket head unit when I purchased it. It's a JVC single DIN and they replaced the lower deck with a blackout panel. I would like to know how to change this very crappy looking head unit to a 7" flip out touch screen unit and make sure I have the wiring perfect so that I'm getting the most out of my Mach 460 audio system. I need to know what to do to make sure that the whole system will work the way it was intended when I change the head. Help?? I don't have a big budget, so changing the whole system isn't an option.
