1. Select your device model (for example, HDS Pro, Elite FS, HOOK Reveal, etc.) and download the latest software update for your unit. (Lowrance Downloads)

2. Copy the downloaded update file. Do not rename or unzip the file unless the download instructions specifically tell you to.

3. Turn off your Lowrance unit and insert the microSD card.

4. Turn the unit back on. Most models will detect the update automatically. If it doesn't, open the Files/Browse menu, select the SD card, and choose the update file. Follow the on-screen prompts. (Lowrance Downloads)

5. Wait until the update is complete. Do not remove power or the SD card during the installation.

6. After restarting, verify the new software version by opening Settings → System → About (or the equivalent menu on your model).
