What is the difference between GPS on your phone and GPS on a stand alone unit?

I inheirited a stand-alone GPS unit (pretty basic) from a friend and I'm curious about the difference between this (which has a battery life that is much longer, and I could definetly see a reason for using it), and a standard smartphone with GPS. For instance, often I can't use the GPS on my smartphone without data turned on as well. Is this so the maps can be downloaded? What would I need to do to be able to have my smartphone's GPS working when I am abroad without data roaming?
(I feel like this is a dumb question, so thanks for humoring me!)
