About this app

Find out what’s really going on under your hood with Garmin Mechanic.

Get insight into how your car is performing with the free Garmin Mechanic™ app. Use the Skidpad to measure lateral acceleration, and track your speed and distance using GPS.

Taking a trip? Garmin Mechanic tracks your trips and calculates total distance, average speed, and estimated mileage to help increase fuel savings. Got more than one vehicle? You can track and collect data on multiple vehicles.

At the pump, enter your fill-up data and track average mileage, total fuel used, fuel cost, cost per mile and more. Set up service schedules for maintenance on all your vehicles, and get notifications when service is due.

Expand your toolbox by pairing the Garmin Mechanic app with our ecoRoute™ HD module (sold separately) and gain access to real-time performance data, including live gauges showing RPM, throttle position, intake pressure, manifold vacuum, boost, instant economy, battery voltage, real-time estimated power and torque, and more. Evaluate your driving style with the Eco Score gauge.

Create gauge sets and save them as Dashboards, and instantly recall them for different driving modes (e.g. towing, economy, racing).

Measure your vehicle's performance with the Acceleration/Dyno feature. Measure 0-30, 0-60 and 1/4-mile times, torque and horsepower.

With the ecoRoute HD module, Garmin Mechanic also calculates your instant and average fuel economy, and checks your vehicle’s self-test status for emissions certification. The vehicle diagnostics feature reads and provides descriptions for over 6500 error codes and resets your vehicle’s Check Engine light.

Export all your vehicle information (including fill-ups, service schedule, service history, sensor data, diagnostic data, acceleration runs and more) to view on your computer.

Excellent App. It worked well until Android evolved and the App lost connectivity with the Garmin Echo HD (the Bluetooth does not find the device anymore) I don't understand why Garmin keeps doing this with their products: they abandon the projects and leave customers with a 100us$ hardware good for nothing 😡 How hard would be to just follow up the Android evolution and update the App?

This will still connect with my pixel, but the information is so flaky. Fuel economy gives you speed and vice versa. Fuel economy units are wrong. All other functions and data have disappeared. It used to be wonderful paired with my nuvi but that doesn't work anymore either. Sad that such useful tools were abandoned by Garmin.

It's a great app. Sadly, it's not updated anymore. I used it religiously on my Samsung GS5. Garmin claims it was because the Bluetooth plugin didn't sell, but as I always tell Garmin reps, it helps to advertise something which Garmin didn't. Even some models of Garmin GPS supported the Bluetooth plugin. But it was so poorly documented.. Didn't sell? Gee what a surprise. But this is a great app and it's too bad. Garmin should release it to the public domain to devs interested it
