JLR now have a 2 or 3 year subscription for this system, if not renewed then owners can download their choice such as Google, Garmin etc (download at a cost of course) after deleating the existing, So something similar maybe available, if available for a Freelander 2 I don't know. Perhaps your owners handbook or the dash screen menus will help.
GPS has nothing to do with the engine so may be better off in the Freelander Forum.
