Trouble with voice commands and volume

Voice commands

Say "Ok Google," press and hold the voice command button on your steering wheel, or select the microphone  to talk to Google.

Here are some things you can try if Android Auto is having trouble understanding voice commands:

• If you're using the voice command button on your steering wheel, make sure to press and hold until you hear the beep. If you don't press it long enough you might exit Android Auto and have to restart it.
• Start speaking after you hear Android Auto beep. The beep is confirmation that Android Auto is listening. 
• Try to minimize the noise around you when you speak.
• If you're using an aftermarket receiver, make sure your microphone is working properly. You can check with your installer if you're not sure. 

Volume

In some vehicles, the volumes for navigation, media, and voice may be controlled separately.  Please consult your vehicle owner’s manual to learn more.
