Just wanted to share:
Had a problem getting video to record from my 1243xsv using an IPhone 12. Short of it, I could view the screen on my phone, but when tapping the record icon the screen would go black. Talked to Garmin - solution was to turn off “cellular data” in Helm properties. It worked. Garmin said a change would be forthcoming to remedy the issue. Anyone else have this issue pop up?
