Hello, looking at a 2015 SR5 4Runner for the wife. It does not have navigation included. Normally I would slap in a aftermarket unit with nav but the wife wa ts to keep the factory look. What do I need to add factory nav to this SR5? Is there a way to unlock it on the current system? Add a module in the dash? Replace with a factory unit that has nav installed? If I replace with another factory head unit is there anything else that is needed or nust swap the headunits?
Thank you for any help.
