if toyota says the part is discontinued, that's likely as far as things can go, unfortunately. it's a toyota-specific flavored head unit.

you could attempt to try if any other 2014-16 scion models have an updated map card, and cross your fingers it's the same software as in your fr-s, but you'd likely need to purchase the map card at full price, it'd likely not be returnable, and there'd be significant risk the money would be wasted.
