Bang & Olufsen has quietly updated their Beo5 remote control and listed the new Beo6 version on their site which is now equipped with wireless setup. The instructions related to the Beo6 unfortunately dont give to much away as regards new features of the control and it seems as though the older model and new are fairly similar.
The Beo6 is however fully compatible with Beo5 right down to using the exact same menus and controls, the documentation on the site indicates that the Beo6 can connect to your Wi-Fi network to enable 2-way control with other Bang & Olufsen devices supporting a 2-way communication.
However no setup instructions are listed for the Beo6 and the connections would most likely need to be carried out by a Bang & Olufsen retailer. More information on the Beo6 is available from the Bang & Olufsen Beo6 webpage.
