Ok getting a new car, but didnt want to pay the 2000 for the built in navigation system although it wouldve been awesome. But too pricey. Was told by others that a portable one is much cheaper, even after installation.
So I need your advice on which ones work the best. I live in San Jose, CA so I need one that works best in the USA (I dont know if the country makes a different, but I wasnt sure if I bought one designed specifically for Canada if everything would be in kilometers and not allow me to make U turns, which are perfectly legal here

).
Thanks,
me
