Has anyone figured out what information is conveyed by the different number of beeps from the RTL510 radar?
Garmin support says:
The device beeps one time when the first vehicle is detected. After the threat is cleared, the device beeps again when another vehicle is detected.
That's definitely not what happens with my Edge 130. Most often I get two beeps when a vehicle is detected. Sometimes three beeps. Occasionally four. The Edge is displaying the correct number of vehicles, so it's not over-counting. I assume the support information is just out of date, but I can't make any sense of the actual behavior. (It doesn't appear to be related to either closing speed or vehicle size.)
