Yes, it is very possible. If you're still interested I'm offering (under my business OWC Upgrades)
100% plug-n-play harness adapter kits for the conversion.
Apart from that, you would just need the four NAV Parts below from a 2010-2017 vehicle with Nav:
(1) Touch Screen Display
(2) Control Panel Buttons
(3) Faceplate / Climate Panel
(4) NAV Unit / Radio Receiver
If you'd like to know costs and exactly what parts are suitable to convert your vehicle to a 2010-17 NAV Setup, feel to reply back or shoot me a PM.
Harness Adapter Kit Example (factory parts not included, shown for demo purposes):
Example showing the adapter harness connected to the factory connectors on an EX35 and the new nav unit. Would be the same for an FX.
