NOOOO get nav! try seeing your radio screen with polarized sunglasses on! Its also a lot nicer because you can change more settings easier, ipod control is much better, you can set automatic ventilation etc etc etc. The hump isn't ugly, people just need a reason to justify their car and not feel shitty about not having nav.
