The NAV system was not available from my dealer when I purchased my 2011 Prius.Can I buy one and swap it for the basic stereo setup? Or is there more to it?
Search is your friend... Adding the factory nav (used/Ebay) requires nav, JBL amp/speakers, factory wiring etc etc... I don't know anyone who has done that here... Aftermarket navs are a dime a dozen - read about it here...
