8. SOFTWARE UPDATES
To update the D1’s software:

Check the version of software currently loaded on your D1. The software version is displayed
for a few seconds at the bottom of the screen immediately after you press the rocker to
acknowledge the safety message upon power on. It is also displayed in the Settings Menu.

Check www.dynonavionics.com for the latest D1 software version.

If the version number on the Dynon website is higher than the one your D1 currently has,
download the current version from the Dynon website.

Copy the downloaded .d1s file to an SD card (not included). Put the file on a blank SD card.
Firmware updates for the D1 are only a few megabytes, so any size SD card is suitable for this
operation.

Fully insert the SD card into the D1 until it clicks into place, with the SD Card label facing the
back of the D1. You may need to use a small, thin tool – a US quarter works well – to fully
engage and click the SD card in the slot.

Power on the D1.

The D1 will automatically update and display further instructions and status.

Remove the SD card once the update is complete. Restart the D1 using the Power Button.

Confirm that the software is up to date by confirming that the version number shown at power
on matches the version you downloaded from the Dynon website.
