As noted by Consumer Reports, screen size is an important characteristics for GPS devices. Adequate screen size ranges from 4 to 7 inches. When GPS devices have small screens, drivers often have trouble viewing directions and entering addresses.

Real-time traffic alerts are also an important feature of these devices. These alerts are useful for adjusting routes to avoid construction or other traffic-related issues. Similar to traffic alerts, lane assistance is a characteristic that suggests the best lane based on upcoming maneuvers. This feature is valuable in urban areas where multiple lanes are often used.

Text-to-speech is a valuable characteristic used for reading street names and popular locations aloud. Text-to-speech helps drivers keep their eyes on the road, which is important for safety. Text-to-speech also reduces the amount of times drivers glance at the GPS device to observe upcoming directions.

Having a dynamic search feature simplifies the input process. It allows the driver to select an address from a relevant list, rather than typing in the entire address or city. This saves time and makes it easier to operate the device while on the road.
