Quilting didn't seem to make a difference. The vector charts just didn't display until zoomed in. However, I noticed some little "bubbles" at the bottom of the screen
which switches the view from chart to chart. That allows me to switch between all the loaded raster or vector charts, so I can use raster charts for small scale chart viewing or course planning and switch to the vector charts for large scale or for actual GPS navigation
. I like the raster charts because they look more like "real" paper charts, but there's so much more info on a good vector chart. Seems to be an OK system.
Thanks for the help everyone. I've just started using the system (actually just playing with it since my boat won't launch for another 2 months) and I'm sure I won't really learn how to use it until it's on the boat.
