Do you have to update GPS?
But things do change slowly over time. Roads get rerouted or changed for safety, streets get renamed, bridges get replaced, traffic patterns are modified. So, if you use the navigation system often, and drive a lot in unfamiliar places, then it's probably worth updating every four or five years.

What is the refresh rate of a phone GPS?
Consumer devices update gps positions with a rate of 1hz, so one location per second. A higher rate of e.g 10 / s would not make much sense. Positions would not get better, more likely they get worse, however this a theoretical discussion, since consumer GPS chips usually will not provide a higher rate than 1 or 2 hz.

How often do GPS maps update?
Usually, the satellite view on Google Maps is updated around every one to three years. This is because Google Earth takes a lot of time to process an enormous amount of data from various sources. Just like Google Earth, Google Maps may also update in real-time when major events occur or at times of crisis.
