How to adjust the navigation volume on a GL8?

[VonEdward]

When waiting for the navigation system's voice announcement, you can adjust the volume through the in-car navigation voice announcement. When waiting for the OnStar announcement, simply press the white OnStar button to adjust the volume while OnStar is speaking. The owner can directly use the knob to adjust the volume, as there are adjustment buttons on the steering wheel or center console for convenient and quick operation. After the vehicle starts and the center console screen turns on, you can adjust the navigation volume using the built-in volume adjustment function in the vehicle's background system.

I remember adjusting the navigation volume on the GL8 was quite simple last time. When the navigation started announcing the route, I directly used the volume knob next to the steering wheel to adjust it: turn clockwise to increase the volume and counterclockwise to decrease it—very convenient. If the knob responded slowly, I would go to the main menu on the central control screen, open the "Settings" option, and then find the dedicated navigation volume slider in the "Sound" or "Audio" section to drag and set the value. This way, the navigation volume is independently controlled without affecting music or the radio. I also noticed that if Bluetooth calls or CarPlay were connected, the navigation sound might become quieter, so I had to turn off other audio sources to ensure clarity. Regularly checking these settings can prevent distractions while driving, as hearing navigation instructions clearly is crucial for safety, especially on highways. If the volume adjustment doesn’t work, it might be due to the system needing an update or restart—try turning off the engine and starting it again.

Adjusting the GL8's navigation volume, I prefer a hands-on approach. When the navigation is running and announcing directions, I press the volume up or down buttons on the steering wheel or use the physical knob on the center console to directly increase or decrease the volume. It's not a complicated operation, but if it doesn't respond, I proceed to the system menu: start the screen, enter the "Settings" menu, select "Sound Settings," and find the navigation volume option to adjust it separately. I've noticed that in different driving modes, such as Eco mode, the volume may automatically decrease, so after setting the default value, I save it. Ensuring the volume is moderate and not harsh helps reduce driving distractions. I also recommend keeping the software updated to avoid bugs causing abnormal volume levels; if the sound fluctuates, check for loose connections or restart the navigation app. Familiarizing yourself with these methods makes driving more pleasant.

Adjusting the GL8's navigation volume is straightforward. When the navigation is giving instructions, simply rotate the center console's volume knob to control the level. If the knob doesn't respond, access the settings menu, locate the navigation volume slider under the sound options, and adjust it to a comfortable level. Remember, the navigation volume is independent and doesn't mix with other audio. Setting an appropriate volume helps prevent missing turn instructions.
