Phonak Communications has supplied a guide-U wireless tour guiding system to BMW Welt for use at the company's global headquarters in Munich, Germany.

The system is able to guide groups of tourists, corporate guests and VIPs around the company's on-site education centre.

Wearing headphone sets, guests, including those with hearing aids, are able to listen to the guide wirelessly, with the guide-U's batteries lasting up to 13 hours at a time.

The system is also in operation at other tourist and corporate sites around the world including Les Arts Decorative in Paris, and the Sydney Opera House.
