Is the Edge 840 Solar worth it over the Edge 540?

The 840 adds a touchscreen and solar charging over the button-only 540. If you ride with gloves or in rain often, the 540 is fine; if you want faster map panning and touch input, the 840 is the better fit.

How does it compare with the Edge 1040 Solar?

The 1040 has a larger screen and more battery, but it is bigger and heavier. The 840 keeps most of the same training and navigation features in a smaller body.

How long does the battery last?

Garmin rates it up to 32 hours in intense mode and up to 60 hours in battery saver mode, with solar adding charge on top in sunny conditions.

Does the touchscreen work with gloves?

The touchscreen is capacitive and may not respond to thick gloves, but the physical buttons work in any condition.

The unit, a standard mount, a charging cable, and documentation. Sensors and a remote are sold separately.

Can it control a smart trainer or radar?

Yes. It pairs with ANT+ and Bluetooth sensors, Garmin Varia radar, power meters, and smart trainers for indoor workouts.
