Us 5 Camp Posted November 24, 2002 Share Posted November 24, 2002 What are Garmin Data Cards.... are they truly proprietary or are they compatible with an aftermarket card (i.e. lower cost) Also, are the USB card writers required? I assume the GPS's standard serial port would work, albiet at a much slower download speed... Thanks again... "Never have a philosophy which supports a lack of courage..." Quote Link to comment
