Oh you do, but, it just needs a cable, and a couple hours work. That is the easy part as long as you can remember how it goes back together.
The difficult part is, finding a decent fascia surround that doesn't look really cheap, nasty and totally the wrong colour and texture to the rest of interior trim/plastics.
That and finding a decent double din head unit with bluetooth that doesn't look designed to go into a nasty chavved up rice rocket civic, with jumping dolphins, or neon blue idiot lights for every control.
