Need to keep track of your mileage? There may be a built-in solution already in your nuvi. Garmin’s ecoRoute app automatically creates a mileage report that can be viewed on the screen or downloaded from the nuvi as a .csv file. The only trick is you have to select a destination; if you’re just driving around with your nuvi on, the mileage won’t be recorded.

There are 38 nuvi models that come with ecoRoute preloaded. Owners of the 2012 Advanced (nuvi 2xx5) or Prestige (nuvi 34xx and 35xx) series will have to pony up $9.99 for the ecoRoute app.

Before you can start generating reports, you’ll need to go into the app and set it up for your vehicle. After that, you can view the report on screen or connect the nuvi to your computer and open or download the mileage.csv file. The report has a number of fields including Date, Start time, Origin, Destination, Distance and Time. There is more info on the feature in this mileage report FAQ.
