Abstract: A method, system, computer program product, and device for providing telematic services to a vehicle utilizing an external portable wireless device such as, for example, a wireless mobile phone, is provided. In one embodiment, the telematics device collects vehicle data from the vehicle and, responsive to a determination that a portable wireless device is not coupled to a telematic unit, buffers the vehicle data in a memory until such time as a portable wireless device is coupled to the telematic unit. Once the user's portable wireless device is coupled to the telematic unit, the telematic unit transmits the vehicle data from the telematic unit to the user's portable wireless device which then sends the vehicle data to a telematics service provider.
