NAV button
All cars of model year 2015 are equipped with a NAV button. This button is for the Sensus Navigation system. However, the fact that car is equipped with the NAV button does not mean that the car is equipped with Sensus Navigation. If the car is not equipped with Sensus Navigation, the following message will be shown when the NAV button is pressed.
To access the Sensus Navigation system, you need to purchase it. Contact your Volvo Dealer for more information.
