If you have a laptop already then it makes a cheap alternative to an aftermarket nav system but there are too many downsides: Nowhere safe to place it. If you place it on the passengers seat then you get all sorts of reflections - especially if the passenger is holding it and he/she is wearing a white shirt! The screen is nowhere near as bright as the Honda/Acura nav screen. Not easy/safe to make changes while driving. And you have to buy a car adaptor so the battery doesn't fail you. And most importantly, if you have to brake suddenly, you might find your expensive laptop to be in a few more pieces than when you started out.Does GPS for laptop make any sense? For example, am making a round trip from AR through NC and into VA.
I originally thought the same thing, and in a more rural area that may make some sense .fancourt said:. I'm not getting Nav. either but after reading these posts feel may have been a mistake. But then I don't travel much.
