My apologies if I have missed something. Can I load detailed maps on Basecamp that is running on windows laptop?
Recently made the switch from map source to basecamp. When I open Basecamp all I have is a generic map without any detail or search capabilities. (Search works to find imported waypoints) When my GPS is plugged in all is fine. But it reverts to generic map when GPS is unplugged. Import?
