The Garmin DriveCam™ device uses natural language processing to understand the intent of your spoken requests. You can ask questions or speak commands in natural language, using complete sentences. Many example phrases are provided in the manual, but you can experiment with speaking to the device using the language most comfortable to you.
Garmin® voice-activated navigation allows you to search for locations and addresses, start routes with turn-by-turn directions, place hands-free phone calls, and more. You can launch Garmin voice-activated navigation by saying OK, Garmin followed by a request.
