I have to set the Garmin to 'NMEA In/Out' to connect it for navigation purposes, but change the setting to 'Garmin' when transferring waypoints - I'm sure there's a logical reason for this.

MacENC uses NMEA (the standard for marine electronics communications) for plotting real-time position. It uses the proprietary Garmin mode for transfering waypoints, routes and tracks. Unfortunatlly the Garmin transfer mode lacks much of the data that NMEA provides (i.e. satellite, active waypoint/route).

The Navionics chart shows the low-to-high tide region as the same colour as dry land, which considerably alters the shape of the coastline, sometimes making it difficult to recognise. It would be much nicer if it followed the colour conventions of my paper chart to indicate the drying areas distinctly.

I have noticed that Navionics ENCs do not adhere perfectly to the S-57 ENC standard. Please contact me at macenc@mac.com so I can make MacENC handle the Navionics slight differences.
