[TG] [TG11] GPS coordinates save incorrectly

[Tom - Raymarine - Moderator]

Hello Drifter18,

It sounds to me as if you have your Axiom set to a GPS datum other than WGS84. In that instance, the system does an automatic conversion between WGS84 and the configured datum. Unless there is a very good reason and you know exactly what the implications are, we strongly recommend you staying with the default of WGS84, since that's the reference datum for all modern charts. The datum setup is in Home > Settings > Units.

If you've got a WGS84 chart (you almost certainly do) and have been given some waypoints referenced to another datum, I would suggest leaving the Axiom in WGS84 and converting the waypoints/marks to WGS84 before entering them. There are a few online calculators to do that sort of thing, if you know what datum to start from.

If the datum is already WGS84 then obviously something else is going on, in which case please give me specific lat/lon examples before and after entry and ideally a video of the operation of entering the mark so that I can see exactly what's happening.

Regards,
Tom
