According to the product specialist

Pros
The screen is clearly readable no matter the circumstances due to the automatically adjusting backlight.

The clear, extensive Workout Player makes training easier and more efficient.
The Karoo can connect to smart lights, radars, power meters, heart rate monitors, eBikes and even SRAM AXS components.
The Coros Dura Bike cycling computer has a beautiful, clear 2.7 inch colour display with a 240 x 200 pixel resolution.
Up to 2 extra hours of running time thanks to solar charging!
This bike computer has a maximum battery life of 120 hours (excluding solar charging), which ensures it'll last extremely long.

Google Maps integration for smart, adjustable routing.
Cons

The Karoo can be paired with your SRAM AXS group, but not with Shimano Di2.
