Garmin has been the forerunner in the commercial GPS market and has consistently ranked among the top 10 GPS that are sold world wide. GPS products from Garmin are known for their quality, great user interface and for the safety features that are incorporated into each of their GPS systems.

The more affordable the GPS unit is, the smaller the memory capacity will be. A number of the cheapest units will need to have maps loaded on to them by the way of memory cards. Nevertheless, the pricier units will have maps already loaded into their built-in memory systems. If you are looking for a GPS navigation system that has pre-loaded maps, be prepared to pay more than $500.
