Truckers GPS

I am one of many people who drive a car anywhere without GPS for I just couldn't bring myself to spend that much money to buy such latest expensive Navigation System. I have to admit, I do need GSP really for I get lost sometimes especially to those areas that I am not familiar with. I know many people go with the latest already because of the convenience. I won't blame them for it makes so much easier if you know the direction you're going. And I know a lot of truckers are using the truckers GPS especially when they traveled-across country. They surely need the right directions to get their destination faster.
