Certain configurations described herein are directed to a system configured to detect the presence of at least one mobile device within a vehicle and determine if the detected mobile device is an authorized mobile device. In some instances, the system comprises a processor separate from a vehicle engine control unit, in which the processor is electrically coupled to a first antenna configured to receive a wireless transmission from the mobile device when the mobile device is present in the vehicle and transmitting wirelessly. The processor may also be configured to determine if the detected mobile device is an authorized mobile device.
