Garmin ecoRoute HD

Transform your compatible nuvi into a real-time diagnostic computer with ecoRoute HD. This easy-to-install device not only provides fuel and mileage reports, but you get more accurate fuel consumption/conservation data by tapping into your vehicle's diagnostic system. Calculate your carbon footprint, engine performance and more all through your nuvi.
With ecoRoute HD, you not only save fuel, but the vehicle diagnosing capabilities could also save a trip to the mechanic. After completing a simple setup, you can use your nuvi to run diagnostic testing on vehicle systems, such as the battery and drive train, and you can monitor engine data, including temperature and emissions. You'll also receive diagnostic trouble codes and be able to reset your check engine light.
