Have just bought a 2013 fl2 gs. It has the radio display screen in the spot where I think the sat nav is usually placed. I would like to put a sat nav in the space either sat over the current display (I know I would not be able to see what radiostation I was on but I could live with that) or take the screen and surround out and put a sat nav in the space? Can I do either and how would I goabout hard wiring it? Thanks in advance.
