GPS
tomtom all the way. i just got a tomtom one xl cause they are now replacing it with a new model so i got it for $200 from radio shack. they work great and have all different models for more options like bluetooth and traffic if you want to pay a little more. but even the cheap ones work great. once and a while though they will put you at the wrong end of a rode or tell you there is a restaurant where there is nothing, but its not that bad just keep updating like everyone else and they will keep getting better. im not sure if other brands have this problem but overall they are good and cheap
