My question is in regards to the auto chart feature. Now I understand you must graph an area to come up with your map and that you can save it to the internal memory or the SD card. After selecting a Destiination for the data to be saved for later use can it be displayed as the lake master card can through ethernet meaning can I have the data stored on one SD card at a consul and have it be displayed on the unit on the bow. Also while I’m driving at the consul recording the data could I have it be displayed at the bow so when I have graphed the area And i would like to fish I can just hop onto the bow and start fishing with the new data being displayed?
