And isn’t a good old fashioned Road Map just as good – and a lot cheaper?
What's the difference between Sat Nav and GPS?

Satellite Navigation is just to help you navigate and it probably uses a GPS to help with that
and GPS is Global Positioning System which tells you where you are not how to get there
and the road map is much cheaper but kind of a hassle when your trying to get somewhere and you don’t have a copilot

Sat Nav – Satellite Navigation
GPS – Global Positioning System.
GPS is a global navigation satellite system

a GPS ( global positioning system ) tells you where you are in the world
to within a few feet.
a satnav uses gps type services to calculate where you are and then how to get to your chosen location, based on a programmed map

Sorry Fu but you are not quite right.
GPS stands for Global Positioning System which is a collection of US owned satellites originally designed for military use. 3 signals are required to fix a position on the surface of the Earth but 4 or 5 are more accurate.
Sat nav units use the GPS satellites to operate.
I use one as it saves a considerable of time and is more up to date than a map.

A minimum of 4 satellites signals are required to get a position (not 3 like you stated). Also, more satellite signals do not give you more accurate position. Instead, they give you a more statistically confident solution.
Please get do some research before you try to state things as fact.
