As of 2015, advantages of all Garmin Nuvi GPS models over other brands include physical directions, routes within structures, FourSquare information and a multi-touch screen. The Advanced series adds junction photographs, and the Prestige series includes three-dimensional lane guidance and a chargeable magnetic mount.
The magnetic mount attaches securely to a window or dashboard, separating just as readily. Moving the charger to the mount allows the unit to remain positioned and plugged in even without the GPS.
Another convenience of the Nuvi is the capacitor screen that enables pinch and zoom control. This feature contributes to one disadvantage: glass screen is highly reflective and difficult to read in bright light.
Instead of hard to see street names, Garmin's Real Directions uses three-dimensional maps of physical landmarks, structures and traffic signals. Its Direct Access feature shows locations into sites, such as a single gate at an airport.
Many of the Garmin Nuvi features focus on safety. The ability to see a photo of a road junction or hear which lane exits off a highway prevents dangerous last-minute lane changes in complex traffic situations. Infrequent errors in these features are a disadvantage, emphasizing that safety and complete control of the car is ultimately the driver's responsibility.
