Dash will automatically connect with your vehicle to track your driving.
Once you've configured Dash the first time, it will try to connect whenever you're in the car. Just make sure your OBD-II is plugged in, and have Dash running in the background on your phone.*
If you don't use an OBD with Dash, then auto-connect is a work in progress. To see if the feature is available in your version of Dash, go to Dash settings, find the "Driving" section, and look for "No OBD settings."
If you don't want to use Auto-connect with your OBD, you can turn it off. Again, go to Dash settings and look for the "Driving" section. There's also a submenu for "OBD settings," where you'll find the option, as well as a few other advanced settings that most users can safely ignore.
Important to know: whether you use an OBD or not, Dash does not need to be the active app on your phone for auto-connect to work, so go ahead and use Waze or Pandora simultaneously while you drive.
*Recent versions of iOS and Android will sometimes be very aggressive about closing apps in the background; this can interfere with Dash auto-connect. If that happens, just open the app and click connect to log your trip. If you continue to have issues let us know at email@example.com
