^^^ i believe that. my truck has a builtin gps. i find if i've been using it a whole lot, i tend to not be as confident without it. i do use it for going further distances, if nothing else it gives you an arrival time. but i try to not look at it for every single turn needed. its really nice to have just the map function in front of you, a colour, moving map you can look at instead of folding out the paper one.
