I'm using a VAHR with edge 1000 explore and a varia radar. The edge and radar perform as expected, audible alerts and screen display. I broadcast HR from VAHR which displays and records on edge. While broadcasting the VAHR displays HR and is locked. The VAHR is also paired with the radar but nothing happens, I was expecting to get a vibration alert when radar detects vehicles, but no. Am I expecting to much, what function should I expect to get from the VAHR and radar?
