I have the VA3 for more then 2 years, no major complains, I was using it for biking (sensors, HR, tracking and mapping worked OK) two full seasons before I got the 1030 this last winter.
I cannot imagine myself wearing a HR strap when biking, tinkering if I could broadcast from watch to Edge.
Each of the unit manuals saying what to do with watch or what to do with 1030, but no real explanation for these two units specifically.
The VA3 online manual saying:
??? Would this mean the Edge 1030 will "command" back to VA3 when the activity starts? because I removed all biking related apps, sensors and datafields from the VA3 because I got the 1030. Or shall I understand to start the biking activity in VA3 when I start riding, but that means duplicated data in Garmin Connect.
The Edge 1030 manual is not saying how to connect to VA3, at least I have not seen it, yet.
