Settings in Google Maps
Voice guidance level
Set the level for voice guidance, for example, if you only want to hear traffic information and not the next maneuver.
Route options
Set, for example, preferences to avoid road tolls and highways in route guidance.
The above instructions are general and concern third-party suppliers. Availability, design, and functionality may change or vary.
Other settings
Volume for voice guidance
Turn the volume control below the center display or use the buttons on the steering wheel’s right-side keypad. An expandable menu will open in the center display. Set the volume for voice guidance.
Language and units
If you would like to change the language or units used in Maps, you can change these settings in App view 
. Please note that changing this setting will change the language and units used in all of the vehicle’s display’s, not only Maps.
NOTE
Changing languages in the center display could mean that some information in the Manual will not comply with national or local laws and regulations. Do not change to a language you do not speak well, as it can be difficult to find your way back through the menu.
