Looks like CF includes everything you need to install your D3..... Connector cable, install cage, and some other accessories. Most of them are included in the CF price, right? Does any other retailer do that? Or is everything needed to install the unit $$optional$$ with the other sellers? How much does the cable and cage cost separately?

I think cardomain includes some stuff, but not as much as CF. CF includes a "master tech sheet" for your car with detailed instructions on HU & speaker removal.
