A method on a mobile device comprising: receiving an IVIS device identifier associated with an in-vehicle infotainment system, IVIS, during initial pairing of the IVIS with the mobile device; determining and storing, at the mobile device, paired-device identity information associated with the IVIS device identifier; connecting the mobile device with the IVIS; retrieving the stored paired-device identity information associated with the IVIS device identifier received from the IVIS; responsive to retrieving the paired-device identity information, determining a mobile device behaviour from the retrieved paired-device identity information wherein the determined device behaviour is associated with a behaviour profile, the behaviour profile defining one or more actions to be performed by the mobile device when paired to the IVIS; based upon the one or more actions defined by the behaviour profile associated with the determined device behaviour: identifying available services of the mobile device that are accessible via the IVIS; retrieving content for a lock screen on a display of the mobile device when connected to the IVIS, the lock screen identifying the available services; displaying the lock screen on the display of the mobile device; receiving data from the IVIS; and retrieving further content for the lock screen on the display of the mobile device, such that the displayed lock screen further presents the data received from the IVIS. receiving an IVIS device identifier associated with an in-vehicle infotainment system, IVIS, during initial pairing of the IVIS with the mobile device; determining and storing, at the mobile device, paired-device identity information associated with the IVIS device identifier; connecting the mobile device with the IVIS; retrieving the stored paired-device identity information associated with the IVIS device identifier received from the IVIS; responsive to retrieving the paired-device identity information, determining a mobile device behaviour from the retrieved paired-device identity information wherein the determined device behaviour is associated with a behaviour profile, the behaviour profile defining one or more actions to be performed by the mobile device when paired to the IVIS; based upon the one or more actions defined by the behaviour profile associated with the determined device behaviour: identifying available services of the mobile device that are accessible via the IVIS; retrieving content for a lock screen on a display of the mobile device when connected to the IVIS, the lock screen identifying the available services; displaying the lock screen on the display of the mobile device; receiving data from the IVIS; and retrieving further content for the lock screen on the display of the mobile device, such that the displayed lock screen further presents the data received from the IVIS. identifying available services of the mobile device that are accessible via the IVIS; retrieving content for a lock screen on a display of the mobile device when connected to the IVIS, the lock screen identifying the available services; displaying the lock screen on the display of the mobile device; receiving data from the IVIS; and retrieving further content for the lock screen on the display of the mobile device, such that the displayed lock screen further presents the data received from the IVIS.
