Voice Command Feature
WARNING
This feature allows you to command the device to perform actions that may not be safe to do while driving.
Failure to use commands when appropriate could result in property damage or a possible accident resulting in
serious personal injury.
You can control the Garmin SERV and the system devices using your voice.
Say "OK Garmin" to wake up the device. You can then say a variety of phrases to control the system. For
example, you can speak a room name, a device name, and a command, such as "OK Garmin, Kitchen light
brighter."
This is a list of commonly used voice commands, but the device does not require these exact phrases, other
than the wake-up phrase or "OK Garmin." You can try saying variations of these commands in a way that is
natural to you.
NOTE: This feature is not available in all languages.
