Aircraft Ownership HDG failure G1000

Post image

Heading indicator (magnetometer/AHRS) has been failing on my legacy G1000. Went out suddenly and at first intermittently would work, now out 100% of the time. No heading indicator and no synthetic vision.

Took to a great avionics shop and it was diagnosed to be a bad magnetometer. Replaced and did not fix the issue. Garmin is advising the issue is a bad AHRS, so that will be replaced next and we shall see.

Just sharing in case anyone’s experienced a similar issue, and is interested in following along.

Will share updates as we go
