Hi I hope someone can help me?

My question is I am looking to try and put a Sat Nav and DVD system which is combined into one unit it toa ChryslerVoyager. I know it is what they call a double Din unit. Couldanyone tell me if it would fit? Or can you only fit a single din system? Also I notice that the factory fitted radio in the vehicle from the photo's has rounded corners. So I am a bit worried about buying the unit before I get my voyager in March but theunit is for saleat the moment at a reduced price.so I don't want to miss out ona great deal. Any advice would be gratefully received as I can't even see the vehicle until I collect it due to the distance between my home and the dealership. I assume Chrysler do a bezel for none standard equipment?
thanks
