A navigation device is capable of a first level of operation and a second level of operation. In at least one embodiment, the device includes a processing resource arranged to support, when in use, an operational environment. The device also includes a data store operably coupled to the processing resource and arranged to store updatable data useable by the operational environment. The device further includes a communications network interface for supporting connectivity with a subscription-free communications network. The first level of operation consumes less power than the second level of operation, and the processing resource supports an activation module arranged to cause a transition from the first level of operation to the second level of operation. The processing resource is also arranged to use the communications network interface following the transition to the second level of operation in order to download data.
