Hi,

I have the following situation:

I want to use Expedition in Magnetic mode and check the Magnetic mode box under System Settings.

My GPS (uBlox6) sends COG(TRUE) as NMEA0183 direct to Expedition in the RMC message. As far as I can find out uBlox6 does not send any message with COG(MAGN.).

I get HDM (i.e magnetic heading) from Hercules 2000 in magnetic mode.

When I look at Heading-COG in Expedition's Stripchart what do I see?

Heading(MAGN)-COG(TRUE) ?
or
Heading(MAGN)-COG(MAGN) ?

I suppose it would be possible for Expedition to know which NMEA0183 COG messages that are TRUE or MAGN respectively and deal with them appropriately. Is there such an implementation?
