Changing Ford Fiesta Mk4 Radio

Hey Guys,

I've just got myself an 01 Ford Fiesta MK4 and I'm looking to change the radio in it,

currently it's just a standard radio and cassette player, so i want to upgrade it

I've been looking around and I've established that a need a new facia for it, but I'm not sure if it's a single din or double din

This is what the current set up looks like (mines not wooden though)

is that a double din unit? because the facia's i've seen for the fiesta seem to have one filled in

Ideally I'd like to have the radio in one din, and then have a pocket for the second din so i can put ipods in it etc...

If this is a double din can I buy a double din facia , and then one of those universal din pockets inserts for the other din?

Thanks in advance
