I have an ONIX 8SI and I have been building a map of an uncharted lake using my ONIX, AutoChart PC, blank SD Card, and a Zero Lines Card. I have a few areas on my Zero Lines Card Map that need to be filled in to make my map complete. I would like to install my Zero Lines Card Map into my ONIX so I can see the areas that I need to record, and at the same time record the information to an SD Card in the other card slot in my ONIX. I have looked through the instruction manuals and can't find anything that tells me if I can do this. Can anyone tell me if this is possible and if so could you explain the steps needed to complete this task? Any and all information you can share is greatly appreciated!
Thanks, Jim
