Could somebody explain a GPS for an automobile?

I keep getting lost in the city because of unannounced detours and want a GPS to help get me around. What is the best kind? What needs to be hooked up to it? Do I have to subscribe to some service? What's the best kind and is it best to buy one online?

Any advice would be appreciated. Thank you.

    A GPS is a receiver for the Global Positioning System built for the military back in the 80's. There are 24 orbiting satellites that send data over radio frequencies to a receiver (GPS unit), that mathmatically determines your position on earth.

    You do not subscribe to any service.

    Just buy a unit with street directions included with detour capability.

    Garmin, Megellan, and Tom Tom are a few of the good ones.

    You can buy them online, and in stores.

    The things are confusing and most inconvinent.. They always talk when you don't want to hear it! ; ) They are helpful though!
