Never heard of Versio and unable to find any reviews, although the price is attractive. I can't find any reference in the ebay listing to backup camera input or option to add XM receiver which are common features of similar, but more expensive units.
As far as fitting, you would need to get the physical dimensions and compare to known posted installs of other brands using double din install kit. There is a round metal brace at the back of the recess for mounting the radio which limits the mounting depth such that some units will not fit.
