...then can I suggest a JVC EXAD head unit
The entire JVC KD-AVX11 comes in a compact 1-DIN size, including the monitor, making it an easy fit for any type of car.
I purchased one today and can honestly say that it has transformed the sound of my car stereo unimaginably!
It's plays DVD, CD and lot's of other formats too. Not cheap, but worth EVERY penny. It has a funky remote control too
