Step-by-step
Find the code on the display
The menu wording can differ slightly between software versions, but the route and the device-specific Request Code follow the same logic on supported Lowrance models.
Open Settings → System
Select the gear icon on the home screen, then open System. A restricted unit can show “Unit not valid for use in this area” along the bottom of the screen.

Scroll down to Advanced
Move down through the System options and select Advanced….

Open User interface
Expand User interface. Find Show geoFence unlock dialog; it can be set to OFF by default.

Switch the dialog to ON
Enable Show geoFence unlock dialog. This reveals the separate Disable GeoFencing item in the System menu.

Open Disable GeoFencing
Return to System. Select the newly visible Disable GeoFencing option above Advanced.

Copy the Request Code
Photograph the dialog or carefully copy the complete Request Code. Send it with the exact Lowrance model. Compatibility and price are confirmed before a personal code is prepared.

Enter the personal unlock code
Select Unlock code, enter the code prepared for this Request Code and confirm the entry. A code from another unit will not match.

Select Enable
Check the entered code, then select Enable. If it matches the unit’s Request Code and the model is compatible, the regional restriction is removed.
