Discover Media Navigation System Plus (California Ocean 2019); Adding Destinations via SD-Card.

[New2VWCaliforniaOceanLife]

I would like to add 'Destinations' to my Discover Media Navigation System Plus via the SD-Card; POI's generated from POIBase upload ok.

I can use online destinations , however I would like to know how to manually upload destinations from a file based system, namely .CSV file; GPS x/GPS y.

Has anyone done this?

BTW I have already raised a support ticket with POIBase just in case they can help.
