what do you have to do to use an aftermarket headunit with the mach 460 system, i have heard that u have to buy an adapter for it is this true and if so where can i find it.

 

Yes. You will need a wiring adapter (see a post that I answered a week or so ago, cannot remember tag) and an adapter mounting kit you can get from a stereo shoppe. The install is really simple, and will get rid of the problematic 6 cd changer currently installed.
