No. Crutchfield does not supply the regulator or instructions. If you look in the Ultimate Sticky for the AVIC - D3 install it shows you what needs to be done there. The instructions given apply directly to pretty much every head unit Radio Shack usually has them in stock though. It comes with just about everything you need from crutchfield though. Everthing BUT the 5 v Regulator. You can get a extra module for HD radio as well as a module for Satellite radio, but they are extra options and do not come stock with the head-unit.
