    Hi everone

    Im after a bit of info on some maps for my sounder i currently own a megallen gps with blue nav marine charts from esprance around the west coast across the top end to about cairns and its all stored on a sd card same as what goes into the sounder. but the sounder wont read the megallen card. The way it is set out on the card is 5 IMI files each doing a section of the coast line i was wondering if any one had bought the humminbird charts and knows how they are set out on the card if maybe i can convert my charts to get the sounder/gps to read it. thanks a heap guys and girls any help would be much appreciated

    As far as I'm aware, the Humminbird will only support Navionics charts and there is no way to convert other charts so the Humminbird can read them.
