An On Board Equipment (OBE) suitable for mounting on a vehicle comprises an OBE antenna connected to an OBE transmit/receive unit. The OBE antenna is arranged to receive a signal from a station via a first wireless communication link. The signal comprises at least one traffic information message from the station. The OBE is arranged to convert the traffic information message for transfer to an audio output through at least one speaker in an existing audio system of the vehicle wherein said transfer of the traffic information message to the existing audio system is arranged to be performed via a second wireless communication link. The traffic information message is arranged to be picked up by standard receiving means of the existing audio system and to be delivered as a voice message on said speakers through a prioritized channel of the existing audio system.
