I notice today that the Navionics map that i see at my console is not the same map i see on my bow unit. Units are all linked together. The console unit has the actual map card in it. Bow unit does have Navionics chosen for it's source. This is a lake that is there HD version that is why i noticed it. Not as many contour lines on the bow unit along with other things. All of the side menu options seem to be the same. Any ideas?
