Hi all, I was looking to upgrade the headunit in my 2005 Corolla with a 2013 Corolla headunit (not the reverse camera one). I was wondering if anyone had done this before, or weather it is possible.ie. will the headunit fit size wise and will I need to modify the wiring. If the 2013 unit is to difficult to fit, which year model headunit will fit straight into the 2005 I have looked at headunits in car audio shops and I don't like any of them, plus I prefer the genuine look. Any help would be great, Cheers Scott
