I dont think you can just drop in the factory nav system if the car was not built for it. The wiring is totally different and you cant just put in an aftermarket on that year unless you want to rewire the car.
The factory amp is turned on thru data and an aftermarket radio will not do that so you have to bypass the factory amp..
