It also automatically downloads charts from NOAA for the United States. Features include: * Waypoints * Routes * Tracks * Night color modes * Anchor alarm * Automatic download and display of weather (wind & isobar) * Chart measuring tools (EBL/VRM) * Wi-Fi-based NMEA and AIS No purchase is required to view charts. Premium navigation features are enabled during a 7-day evaluation period. After that, an annual subscription is required. Existing one-time purchases retain the features they unlocked.
