Hi, I just installed a Garmin G5 as a backup for my SkyView HDX ( installed with the Advanced Control Module so, no wire integration between them as there is no available serial port to that). However, I noticed that, to match my Skyview altimeter setting (30.17), I had to go to 30.11 in the G5. Is there a way to fix that in the G5 or do I need to go to a shop to do the altimeter calibration test?
