A method for a control device configured to control, using a radio interface for radio reception and transmission, a media playback system comprising one or more zones, each zone comprising one or more playback devices, the method characterized by comprising: receiving by the control device a first radio transmission, via the radio interface, indicating an identifier of a first playback device of a media playback system; based on the received first radio transmission, determining that the control device is within a given proximity to a first zone of the media playback system that comprises the first playback device; based on the determination that the control device is within the given proximity to the first zone of the media playback system, the control device causes display on a graphical interface (700A, 700B, 700C) of the control device an indication of: an identifier of the first zone; and a characteristic of the first zone which is a given media item that is being played back by the first playback device or at least one media item queued for playback by the first zone; receiving by the control device a second radio transmission, via the radio interface, indicating a second playback device of a media playback system; based on the received second radio transmission, determining that the control device is within a given proximity to a second zone of the media playback system that comprises the second playback device; based on the determination that the control device is within the given proximity to the second zone of the media playback system, updating, on the graphical interface (700A, 700B, 700C) of the control device an indication of: the identifier of the first zone with an identifier (702B-C) of the second zone and the characteristic (704A, 706A) of the first zone with a characteristic (704B-C, 706B-C) of the second zone which is a given media item that is being played back by the second playback device or at least one media item queued for playback by the second zone, wherein: the graphical interface (700A, 700B, 700C) displays a playback control region (706A, 706B, 706C) including transport controls for initiating, stopping or modifying media playback; based on the determination that the control device is within the given proximity to the first zone of the media playback system, the transport controls are for the first zone; and based on the determination that the control device is within the given proximity to the second zone of the media playback system, the transport controls are for the second zone. receiving by the control device a first radio transmission, via the radio interface, indicating an identifier of a first playback device of a media playback system; based on the received first radio transmission, determining that the control device is within a given proximity to a first zone of the media playback system that comprises the first playback device; based on the determination that the control device is within the given proximity to the first zone of the media playback system, the control device causes display on a graphical interface (700A, 700B, 700C) of the control device an indication of: an identifier of the first zone; and a characteristic of the first zone which is a given media item that is being played back by the first playback device or at least one media item queued for playback by the first zone; an identifier of the first zone; and a characteristic of the first zone which is a given media item that is being played back by the first playback device or at least one media item queued for playback by the first zone; receiving by the control device a second radio transmission, via the radio interface, indicating a second playback device of a media playback system; based on the received second radio transmission, determining that the control device is within a given proximity to a second zone of the media playback system that comprises the second playback device; based on the determination that the control device is within the given proximity to the second zone of the media playback system, updating, on the graphical interface (700A, 700B, 700C) of the control device an indication of: the identifier of the first zone with an identifier (702B-C) of the second zone and the characteristic (704A, 706A) of the first zone with a characteristic (704B-C, 706B-C) of the second zone which is a given media item that is being played back by the second playback device or at least one media item queued for playback by the second zone, wherein: the identifier of the first zone with an identifier (702B-C) of the second zone and the characteristic (704A, 706A) of the first zone with a characteristic (704B-C, 706B-C) of the second zone which is a given media item that is being played back by the second playback device or at least one media item queued for playback by the second zone, wherein: the graphical interface (700A, 700B, 700C) displays a playback control region (706A, 706B, 706C) including transport controls for initiating, stopping or modifying media playback; based on the determination that the control device is within the given proximity to the first zone of the media playback system, the transport controls are for the first zone; and based on the determination that the control device is within the given proximity to the second zone of the media playback system, the transport controls are for the second zone.
