Portable GPS Units That Beat Your Phone
For most drivers, the Garmin DriveSmart 65 is the top pick because it combines a large 6.95 inch display with free live traffic and built-in Alexa. Its main limitation is the higher price compared to basic models. The TomTom Go Supreme offers a flexible mounting system and lifetime world maps, but its subscription for live services is an extra cost. If you need a rugged device for hiking, the Garmin GPSMAP 66i provides satellite communication and topo maps, but it is bulky and costly.
Portable GPS navigation devices still earn their place on your dashboard or backpack. They work without cell service, have bigger screens than phones, and often include specialized maps for hiking or off-road driving.
We compared the latest models from Garmin, TomTom, and Rand McNally. Owners report that battery life and ease of map updates matter most. Here are the best portable GPS units for different needs.

What matters most
How to choose a portable GPS Consider where you will use the device. For driving, a large screen and free live traffic are useful. For hiking, look for long battery life and rugged design. Off-road drivers need preloaded topographic maps and track recording. Think about whether you need satellite communication for safety.
Battery life and power options Car GPS units often have short internal batteries because they are meant to be plugged in. Handheld models have longer battery life and may use AA batteries or rechargeable packs. Check the battery type and expected hours before buying.
Map updates and subscriptions Manufacturers offer free or paid map updates. Some devices require a subscription for live traffic, weather, or satellite messaging. Look for devices with lifetime map updates to avoid extra costs.
Mounting and screen visibility A good mount keeps the device stable and within reach. Magnetic mounts are easy to adjust. Screen brightness matters, especially in sunlight. Choose a device with automatic brightness adjustment and anti-glare coating.
