Lap markers: inaudible even with tones at full volume. User needs to look down for visual confirmation.
Radar tones: not loud enough but it's also the same pleasant bonk sound used elsewhere in the Garmin. Even the multi-tone could be an eating or drinking alert.
Garmin please allow the user to switch the tones used. I need a different tone for laps and for radar. A pleasant barely audible bonk is not what I want when a car is approaching.
