Hi,
Here is an example route consisting of a set of coordinate waypoints in various formats:
ENBR DCT 6100N/00200E DCT H6101 DCT 613917N0021530W DCT 6152N00356W DCT N62W005 DCT EKVG
It looks like this in the app:
I would guess the N62W005 or 62N005W format is the most widely supported across systems.
Regards,
Stephen
