I am tasked with building a worksheet from which coordinates need to be sent to a Garmin device to create wayponts. I understand the file format is .gpx. I am looking for information on what fields the gpx file requires and how to generate/convert from Excel, xml, csv. It would be a real bonus if someone could point me to a VBA macro from which I can start coding.
I believe that if I can create a .gpx file the Garmin device will let me import it.
