Vcards for Columbus 2018

I had a 2018 Amundsen on the Scout. With that, I could build a vcard fine with just the name (FN) and coordinates (GEO) fields. That was great.

With the 2018 Columbus on the L&K, if I do that, the vcards still load, but I get a "confirm address" screen when I try to navigate to a point.

If I include an ADR field it sometimes works, but not always. And for many points I don't have a postal address anyway.

I want to be able to load a set of coordinates. Does anyone have a set of field definitions that works for this?

I don't have any Windows or Mac boxes, Linux only. So telling me about software is unlikely to help. If you have examples of vcards that work, though, that would be great.
