Navman has created a line of GPS systems that are extremely nice. Its model 510 is typical:
It has a color touchscreen. It has the ability to store every surface street in the United States onboard. It can give you driving directions to your destination, and you can choose either a male or female voice. It is very compact, so it can fit in a pocket. And the price is $499.
