so im going to be buying a GPS for my car. im taking a rather long trip and dont want to rely on printed directions as they are distracting, i have a iphone but the gps in it just doesnt cut it for a long trip imo. so my price range is 2-300, and i know nothing about what the good ones are or what to look for. so if you guys could recommend some good ones, im going to try and find a good deal this friday on one. thanks
