like everyone saying its an expensive mod, unless you can get one relativly cheap like on ebay. sorry not trying to rub this in but i did mine from single to double and bought the whole console and facia from ebay £70 bargain. fitted myself too. just take your time and all will fit in perfect..
climate control comes out and when you put the double din in it sits in its place. and goes in easy, have a look at my readers ride i have mine on there.
good luck.
