And what model of Varia are you guys using?
For garmin, a kind of “WiFi” round bar looking thing stays on the top right corner of screen, which is persistent and stays there no matter what screen you’re on. When it detect traffic behind, the head unit beeps (multi tone or single tone configurable), left and right edge of the screen turns orange-to-red depending on the cars’ differential speed to you and a bar with dot(s) representing car(s) appear on the right side of the screen (configurable for which side of screen to show up). When car(s) pass the colored edges turn green and disappear.
As @
WhyFi mentioned, the top one is the current model (RTL510). Do watch DCR and GPLama tube video reviews. You’ll have a much better idea than what I’ve summarized.
