GPS Navigation

Display & Data Entry

The GPS screen should be large and glare-free (optional sun visors are available — check with the manufacturer), showing basic information such as map view, current or arrival time, distance to the next turn, current street name, distance to destination, and current speed (some units also show the speed limit).

Check how easy it is to enter addresses and routing preferences — is the keypad user-friendly, does it support voice activation, is it Bluetooth-enabled, does it offer remote control?

Installation, Portability & Features

Consider how easy the unit is to set up and remove (portable GPS units are a target for thieves) — does it come with a case or screen protector? Most manufacturers offer these features, but confirm before buying:

• Battery for short-term use away from the vehicle (a couple of hours)
• SD memory card slot
• Option to download map data for other countries
• USB PC connection
• Storage of your "Home" address and traffic updates
• Advanced navigation: fastest/shortest route, exclude highways or toll roads, alternate routes to avoid traffic
• Display of car speed, speed limit, distance to destination, and ETA
• Street name and distance to next turn, two- or three-dimensional map display
• Volume control for voice instructions
• Points of interest (POI): schools, police stations, parking, fast food, post offices, gas stations, airports, train stations, hospitals — plus the option to add your own
• Advanced lane guidance for complex multi-lane maneuvers
• Multiple languages and voice/accent options (French, Spanish, German, Italian, Swedish, Danish, Dutch, and more)
