I have watched numerous videos on how to do this but none seem to work. Is there a certain we card to use? Also do have to put we card in a computer and format it to fat32 before u start or by putting it in the Garmin does automatically format it for you. And when u put we card in the Garmin to begin with are there any certain buttons to push to get it formatted? See if Im right format it in Garmin then upload waypoints from lowrance then download to Garmin. This has not worked so far. Just saying.
