Get Android phone instead of GPS?

[FREDERICK F. M]

I have the Androids and it has GPS and Google maps and as you might expect the android screen is quite small and hard to manage if you are driving. The gps/maps for your car is a bigger screen and easier to use 'on the fly'. It is designed to be seen from the dashboard and programmed specifically for traveling. I use the android GPS for my work though. I Work with realtors and have to find streets and ;places and call them. I don't know of one 'instead of the other. The both have their own separate advantages and are probably best used in their own right.

Instead of buying a GPS system for my car I heard I could get an Android cell phone with free GPS instead? Is that true? How well does that work in the car?

I currently have an ATT prepaid phone. Does Android offer prepaid service instead of contracts?
