Computer-implemented methods, systems and apparatus are disclosed for providing a notification when a vehicle has been accessed by an unauthorized person. An onboard computer system of a vehicle is activated in response to a trigger event indicating that the vehicle has been accessed. It is determined whether an authorized consumer electronics device (CED), that is associated with an authorized person, is connected to a wireless communication interface of an onboard computer system. When an authorized CED has not connected to the wireless communication interface, a notification message is communicated that indicates that the vehicle has been accessed and that an authorized CED has not connected to the wireless communication interface.
