Best part is data logging, You can actually data log your car before and after each mod to see if there is any difference. For example, with the intake wars going on with different manufacturers, i data logged my G37 with 3 different intakes to see which one had the most significant air temp drop during normal and aggressive driving. (COLD AIR INTAKE DOES MAKE A BIG DIFFERENCE)

As for the Navi, If you have a base model with without the bose, its easier to just replace the head unit to a double din with NAVI because you don't have to spend money to change the cubby. If you dislike the cubby that much then you have to get someone near your area to make a custom bracket just like what we did. Or you can always drive south to us and we can custom fabricate one for you
