The compass-calibration control is worth locating before you need it. Garmin's LiveScope 2 installation instructions explain the prerequisites and the on-screen process; your exact installation and transducer orientation matter.
Use the instructions for your system
This guide follows Garmin's LiveScope 2 compass-calibration instructions, version 4 dated October 2026. It is educational coverage of that manual, not an announcement of a newly released firmware version.
Find the calibration control
From an applicable sonar view, Garmin lists Options → Sonar Setup → Installation → Calibrate Compass. Follow the display's calibration prompts. The manual specifies a full one-and-a-half boat rotations during calibration, even if you begin turning before starting the procedure.
Check the prerequisites first
Garmin requires the transducer deployed in the water and enough separation from the trolling motor to avoid magnetic interference. It warns that mounting on the motor can prevent compass operation. It also recommends a heading sensor such as SteadyCast for best results. Calibration must reach sufficient quality before the internal compass is enabled.
Changing orientation deserves another check
The calibration applies to the transducer orientation used. Garmin says a change of orientation may require recalibration. Keep this separate from assumptions about where the boat is headed: a transducer can be aimed independently of the boat.
A useful record after calibration
Our suggestion is to save the complete transducer and display model, software versions, orientation and the outcome reported on screen. Add a brief note about the installation, including any heading sensor. That creates context if you later change a mount or ask support a question.
Do not treat a completed motion alone as evidence that calibration passed. Use the actual display result. If the process does not complete, return to the exact-model instructions and manufacturer support rather than inventing a numeric correction.
Keep the procedure manageable
Choose a suitable safe area and follow the boat, motor and sonar instructions. Read the full Garmin procedure before beginning. This article does not prescribe a universal heading offset or promise that calibration resolves every image concern.
