I have the Navidon one and it's bitchen, 3d touch screen, will give me restaurants, gas stations, just about anything I'm looking for while on my path to destination, it's portable!, full color, provides you with traffic warnings and alternate paths suggestions way ahead of where your going, I'm telling you it does it all and everything you / a dad could want!..

Trust me!.. The stupid bastard even tells me when I'm speeding!!

it's like the wife you can live with!..
