I've had problems with interlink disconnecting. Humminbird sent me directions on how to 'reset' the interlinking that should fix it. First step is to export all my waypoints to an SD card.
I put an SD card in the slot on the unit and went to Nav menu and selected export all data. I confirmed export and it said all data was exported fine. A profile text document and MATRIX folder with a DATA.HWR file was created on the SD Card. Next step was to be sure I had all my data by downloading it into humminbirdPC. I put the SD Card in the computer and a tab came up for downloading the data to PC. When I do this it says "Download DATA Error" and nothings happens. What should I do now?
