Viewing Radar on the Varia App
Go for a ride.
The radar information appears on the active data screen.
The vehicle position 
moves up the screen as a vehicle gets closer to your bike. The threat level banner 
changes color based on the potential level of threat. Green indicates no vehicle is detected. Amber indicates a vehicle is approaching. Red indicates a vehicle is advancing at a high rate of speed.
TIP:
The line next to the vehicle also indicates the threat level. A straight line changes to jagged with a red threat level.
