Hey, yea I have seen this mod and read the how to on it, it is located at

I do not believe that it will work on our cars because it is specific to the OEM Mach 1 radio since you have to solder into the board. I have a friend with a mustang and he told me about the site, some pretty cool stuff if you have a stang.
