A navigation system includes: a hearing device configured to be head worn and having loudspeakers for emission of sound towards ears of a user, and accommodating an inertial measurement unit for determining head yaw, when the user wears the hearing device in its intended operational position on the user's head; a GPS unit for determining a geographical position of the system; a sound generator connected for outputting audio signals to the loudspeakers; and a processor configured for: selecting a POI in a forward looking direction of the user based on the determined head yaw, and controlling the sound generator to output the audio signals that represent spoken information on the selected POI. |
