A navigation device (200) capable of a first level of operation and a second level of operation, the device comprises a processing resource (202) arranged to support, when in use, an operational environment (506). The device also comprises a data store (214) operably coupled to the processing resource (202) and arranged to store updatable data (750, 752, 754, 756, 758) useable by the operational environment (506). The device further comprises a communications network interface (232) for supporting connectivity with a subscription-free communications network (704). The first level of operation consumes less power than the second level of operation, and the processing resource (202) supports an activation module (228) arranged to cause a transition from the first level of operation to the second level of operation. The processing resource (202) is also arranged to use the communications network interface (232) following the transition to the second level of operation in order to download data.
