OK, by fiddling with the corrupt links I have just
partly answered my own question. This is what I eventually found in Garmin's FAQs:
Question: </SPAN>Can I plan an aviation route or flight plan on the computer and transfer it to the GPS?
Answer:
There are several Garmin devices that will import flight plan information created on a computer. Currently, the following products with the lastest software support imported flight plans:- G1000
- 400W-500W series
- G3X
- GPSMAP 696 / 695
Garmin does not sell or provide programs that can create the flight plans. However, flight plans created on Jeppesen's FliteStar and Seattle Avionics' Voyager programs are compatible.

So Jepp's product and Voyager(?) will both do what I want. That does not answer my original question about formats, because I might not choose to buy
either of these packages! So I would still love to find out:
- What are their output formats (so I can search for other packages using the same)?
- Has anybody actually done it, using one of these packages or any other?
