Peugeot Cab Radio Question

[Hawkmoon]

Hi, can you fit double Din radio/dvd/sat nav players into the cab of Fiat/Peugeots? Mine is a 2009 model that has a standard size radio/cd player with a same sized holder/recepatcle above it. So I was wondering if the radio & receptacle could be removed to be able to fit a double Din all in one unit like those on the link below : -

Any advice gratefully received
