Hi everyone, searched the forums but did see any discussion of why folks choose GMU-22 vs. GMU-11 for your magnetometer. Garmin pitches GMU-22 for a/c with >250 knot top speed so seems like GMU-11 would be fine for an RV. However, I've seen numerous builder logs where they opted for the -22. It's a pricey upgrade so wondering why. If you have a -22 in your RV it would be great to know why you went that route.
