I have a Lowrance 3300c. Can I copy a chart from Maptech to the SD card used by Lowrance. I cannot connect my GPS to the computer but have a USB cord to the LEI MMC/SD card reader. Then I would like to put the card in my 3300c and see my charts, are they compatable.
Our charts can only be loaded into a Northstar unit or be used with a desktop or Laptop. Our data cannot be loaded into the memory card or any chip that your GPS reads.
