Well, to really be fair, you paid more than $375 net because when you sell that car you lose the Nav. Maybe you get more money for the sale of the car then you might get without Nav, but with the handheld unit, after selling the car you still have the Nav unit. I do like the look of the built in Nav on a car, but I agree that they are generally way too expensive. If it breaks, you have to take it in to the dealer as opposed to just sending the item in for replacement. And if the car were to be totalled, the portable might be salvageable (and if not, renters/homeowners insurance covers it), while with the built in you will lose the unit.
