Using the Navdy app you can keep your Navdy display software up to date. First, ensure you are connected to the display in the top right hand corner of the app. Go to 'Settings,' and click on Navdy Display. Tap on 'Check for updates'. If there is an update available, you can download the update to your phone, and the app will transfer it to your display.
Once the update is finished transferring you can complete the update when you turn off your display by selecting 'Install and Shutdown'. This will install the display with the latest software and then shut down the display.
