I have a Megane II 1.9 DCI 120. I would like to change the factory fitted stereo with a new one, but im having trouble find a fascia to fit my dash.I have attached a picture on my current Stereo.

I have seen a single fascia but i would like one that also has a cover for the old multi changer. Any help finding one would be greatful.
One last thing im looking to get this http://www.caraudiodiscount.com/deh-600bt-cdmp3-player-with-bluetooth-p-12815.html
Would i also be able to still use the steering wheel buttons....??
Thanks Again
