thanks for the reply HBG. I marked most of the way points on Humviewer. Then transfered them over to HumminbirdPC. I had earlier on had a recording on the card but took it off and stored on HBPC. I was trying to see if that would make a difference but it did not. All that is on there now is the waypoints. Everything was loading fine. Have not had any problems. I just keep getting the message. Is this going to be a problem if it continues? I have not updated My unit yet since I got it. Will the software update help with this? I figured I would update it after I got everything like I need it and have learned how to use everything and then update it. Trying to take it step by step and not over complicate things.CF
