Each chart provider sets their own licensing terms. We urge them to be as flexible as possible. Navionics tends to be quite strict with their data. For example you cannot copy one of their cartridges and expect it to work.

X-Traverse does allow one activation for the Navionics charts, however, one can download the chart for up to twenty four months after activation. Once downloaded, charts from x-traverse can be used without any time restriction.
