How to update Lowrance software
A conservative preparation checklist for compatible Lowrance displays. Always follow model-specific manufacturer instructions where they differ.
Record the current state
Photograph the model label and software-information screen. Export waypoints, routes and trails.
Choose the exact file
Match the full model family and generation. Read release notes and avoid similarly named files.
Prepare media and power
Use suitable, healthy storage media and stable power. Do not update when the battery or supply is uncertain.
Install without interruption
Follow the on-screen sequence. Do not remove power or media during a write operation.
Verify the result
Confirm software version, sonar sources, charts, network devices, language and saved user data.
Check the device before changing software
Send the exact model, current software version and the change you need. You will receive a model-specific answer.
