bump for Pioneer IMO.
I would imagine any aftermarket single/double din unit will require an adaptor, (plenty available).
Screen? Size? Sat Nav? Touch Screen? Power Output? Channels? Connectivity(Blutooth etc)? Adjustability?
For my search I picked out the key requirements I needed, then googled issues/problems with all the head units on my wish list until I settled on what seemed to be a universally issue free candidate.
My personal search required Bluetooth, PreOut for Sub, fine control of sound frequency, balance, dB etc..result Pioneer DEH-80PRS
