• The Exclusive Data: If the signal strength is less than 3 bars, Auto Mute will drop to 0% volume (inaudible) after 5 seconds. If the signal is 4+ bars (full strength), Auto Mute only reduces volume by 50%.
• User Implication: You might miss a weak I/O radar shot if you rely on Auto Mute. The exclusive recommendation: Disable Auto Mute for highway driving.
