Hi Everyone. I am going to be a new Prius Owner tomorrow. Found a new 2012 Blizzard Pearl on Dark Graphite Package Five. Doesn't have the Advanced Technology package and the only thing I miss from that is the Premium 7" Nav. I hope i'm gonna like this because my mix of cars is a Mercedes E550 4Matic, a Toyota Tundra Double Cab and a Toyota Solara SLE V6 coupe. Anybody out there done a Premium HDD Nav swap and taken out their Entune?
