My speedo LCD backlight has finally died in my 2009 XF, and now I can really only tell my fuel level at night. I know that any replacement will need to be reprogrammed (with keys) at the dealer, but does anyone know if the newer year speedos are compatible? Not only do the newer styles have brighter colors, I'd rather not go through the expense of swapping out a part with one just as old. Even a 12 or 13 would be a nice upgrade.
