Abstract

A wireless unit or hub for a vehicle includes a wireless communication interface, such as a Bluetooth® interface. The hub stores profiles for wireless devices that can actively interact with the hub. The wireless devices, which can be cellular phones, headsets, portable music players, and Personal Digital Assistants, are capable of providing audio data, visual data, or both to the hub. The hub monitors for wireless devices in a personal area network of the hub. Based on the profiles, the hub establishes wireless connections with the wireless devices. Using an arbitration scheme, the hub controls the delivery of audio and/or visual data provided by the wireless devices to one or more modules communicatively coupled to the hub. The modules, which can be a user interface module, audio module, visual modules, navigation system, and vehicle entertainment system, are capable of delivering audio, visual, or audio-visual data in the vehicle.
