You may register up to three (3) fixed locations (5 in StormWatch+ 4.0), which means that they do not change no matter where you and your device are located. They can be set using city/ST, street address, zip code, or current GPS location. When a GPS location is set, that location remains set – your GPS location is not “followed” to avoid draining your battery. You may re-register locations as many times as you wish, overwriting previous locations.
In addition, you may use SW+ EnRoute to "follow" you and let you know when you enter a severe weather warning. For more on EnRoute, click here.
