If you want leather and the bose I beleive you have to get a Touring Model...

If you want the Nav I would definatly get it now, or you will have to get a aftermarket one later which would probably cost more money time you get done with installation...

Definition of Test Pipe: A short piece of exhaust pipe that's designed to replace a catalytic converter in an exhaust system-supposedly while you test the results of the switch (See Catalytic Converter). Test pipes are illegal and you can be fined if you're caught with one on your vehicle.
