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 . <EOS>
