Abstract: A configurable module adapted for coupling to a host device comprises a stored user interface which is uploadable to the host device when it is coupled to the module. The user interface allows the module to be configured via the host device. The module may be coupled to a plurality of different host devices, including devices having a Graphical User Interface, such as a mobile phone, PDA, and laptop or personal computer. The module may be a digital audio broadcast (DAB) module including a DAB receiver. Alternatively, the module may include a wireless transceiver, such as a short range point to point, point to multi-point, or mesh wireless transceiver, for coupling the module to a network of wireless nodes, which may be the same or different. This module can also function when not coupled to a node, if configured by the host device or from prior connection with a node.
