This is not a problem ! Since the car adapter is designed to work with only one vehicle, you will have to contact the drusteam to report your change of vehicle and authorize the connection to your new car!
When you connect your device to your new vehicle, the app will automatically guide you during the installation. You will keep your driving statistics and the maintenance will be related to your brand new car ;-)
So don't hesitate to contact us at firstname.lastname@example.org.
