Anyone got any good ideas on a nice entertainment set up for my beast?

I fancy a dvd system but, not sure wether to go rear headrest monitors or motorised dash (like bones) or maybe a cd unit at top and dvd unit under that with the 3.6 inch built in screen (looks nice although a wee bit small!! lol)
Also would my standard (grundig i fink) cd changer be ok with a new cd headunit?
like this unit
