We provide GPX files on our Fishing & Dive Sites Memory Card that are a universal format read by most compatiable software programs.
You will need to install on your computer companion desktop software for your GPS model then import our GPX file into the software. After importing, you need to export or save the file to a SDTM card compatible with your unit.
Be sure the manufacturers software can read GPX files and make sure the memory card is the right size for your unit. Contact your manufacturers support line if you are unsure of the card size you need or conversion procedures.
