Can you help me go turn off start and stop. Activate navigation. [XC70 2016]
For your car both actions are possible. First you need to decode CEM PIN, more info here: https://d5t5.com/article/volvo-cem-pin-code
After this you need to go to Car configuration and follow this: https://d5t5.com/article/volvo-navigation-activation-sensus-connect
The Stop/Start you will find on the same place, where you find the Navigation activation.
