So.. DIN-I ?

I'm willing to bet that it is. I know that my car was built for the US and yours was not, but the photo makes the dimensions seem exactly the same. If you get into that dash I'm almost certain you'll find pre-drilled holes (2 on each side) for a DIN-I install.

As I said before, I wasn't able to use the trim plate for the face of the unit I installed there, but since the face is black and the plastic of the console is also black, it still looks quite nice. If only I owned a digital camera to take a picture.

Also, a very wide range of aftermarket head units available appear to conform to I, E, and J standards. So you shouldn't have any trouble finding something with the features you want that will fit.
