Personally, I would not go to the bother of installing an OEM NAV. Simply buy a GPS unit and stick it to the windshield. The Garmin in my Tacoma gives better directions, has more useful traffic info, displays better graphics, actually understands spoken addresses, and has lifetime free map updates. It was also 1/6th the cost of the NAV unit in my '16 Limited. The NAV unit is the most disappointing factor in my car and if I ever get another Subaru I will not get the NAV option. In addition when (IF) I get rid of the Tacoma, the GPS stays with me, not the truck.
