Edge 25 vs. Edge 20
The market offers two similar models: the Edge 20 and the Edge 25. However, the Edge 25 is the superior choice. The Edge 20 lacks Bluetooth connectivity, preventing it from interacting with smartphones and supporting essential accessories like heart rate monitors, cadence sensors, and speed sensors.

For a small price difference, the Edge 25 offers significantly enhanced functionality. The additional features provided by Bluetooth integration make the Edge 25 a far more versatile and useful device for most cyclists.

Main Features and Buttons
The Edge 25 boasts an intuitive button layout. The top left button powers the device on and off. The bottom left button navigates back through menus. The bottom right button scrolls down through options, and the top right button activates selected features.

The device's functionality is easily accessed through this simple and efficient button system. The buttons are well-placed and responsive, ensuring effortless navigation through the various menus and settings.
Navigation and Courses
Surprisingly, this small device supports course navigation. While it lacks onboard map data, the Edge 25 can guide you along pre-loaded courses downloaded from Garmin Connect. This is a useful feature for following planned routes or sharing rides with others.

Simply upload a course to the device via Garmin Connect, and the Edge 25 will provide turn-by-turn guidance. It's a surprisingly robust navigation feature for such a compact device.

Settings and Data Fields
The Edge 25 provides extensive customization options. You can configure Auto Laps, Auto Pause, and Auto Scroll for convenient ride tracking. Importantly, the device features two customizable data screens, each displaying various metrics like time, distance, speed, cadence, calories burned, and elevation.

This level of customization allows cyclists to tailor the displayed information to their specific needs and preferences. The flexibility ensures you can track what matters most during your rides.

Connectivity and Sensors
The Edge 25 leverages ANT+ for sensor connectivity. This allows for seamless integration with ANT+ compatible heart rate monitors, speed sensors, and cadence sensors from various brands. Bluetooth connectivity enables smartphone pairing for notifications of calls and texts.

This dual connectivity option ensures comprehensive data tracking and smartphone integration. The compatibility with multiple sensor brands makes the Edge 25 a versatile choice for various cycling setups.

Garmin Connect and Segments
The Edge 25 integrates with Garmin Connect, allowing for data synchronization, course downloads, and segment tracking. While it doesn't support Strava segments, it does support Garmin segments, enabling performance comparisons with other users on the same routes.

The Garmin Connect integration provides a comprehensive platform for data analysis and community engagement. The segment tracking is useful for setting personal goals and competing against others on specific sections of rides.

Conclusion
The Garmin Edge 25 is an excellent compact GPS cycling computer, particularly considering its value. Its small size and straightforward design make it easy to use while offering most of the features of larger models such as heart rate tracking, speed and cadence data, and smartphone notifications via Bluetooth.
