I did all this, but it did not work. The icon was still facing in all different directions. Some time correct. Some time a little wrong. Some time terribly wrong.
After discussing the issue several times with Garmin employees I bought a Garmin Marine Satellite Compass MSC-10. (By the way, super thanks to the fantastic support from Garmin!)
The installation of the MSC-10 was straight forward. I removed an old GPS antenna, and used that location for the new compass, that also gives the position coordinates (so two antennas not needed). Connecting to the NMEA-200 is also easy. Then you need to go into the settings on the plotter for telling it to use the signals from the new unit.
Sea trial, and sea trial again, confirming that the MSC-10 solves the crabbing problem on Garmin chart plotter.
Is it worth the price?
The MSC-10 is an expensive unit. Is it worth the money? That depends on how big the error is in your case. It also depends on how you use the boat and what you can spend. I am very happy I bought it. I use the electronics a lot, and when I am caught in fog and dark on a remote location this might save my life!
