You are right but what if the only computer you have has linux on it.which thats all I have and the way I did this (if you try this then your on your own)was that I used a program called wine to allow humminbirdpc to run under that enviroment.and I was able to upload and down load to my helix from humminbird PC within wine on linix. Im trying to upload waypoints that were saved in helix to googleearth pro but Im having issues with the depths that are saved,and cant figer out how google earth pro accepts the data.From what I think is happening is googleearth pro does not reconize the depth data....
