A portable electronic device can be used to present vehicle-specific information to a user. The portable electronic device can receive a message transmitted from a vehicle, the message including a unique vehicle identifier such as vehicle identification number (VIN). The portable electronic device can identify content based at least in part on the unique vehicle identifier, and present the content to the user. In some instances, the content may be presented to the user as audio output and/or visually on a display screen. Input can also be received from the user, and the portable electronic device can identify the content based in part on the received input and in part on the unique vehicle identifier.
