I have just started experimenting with OpenCPN
. What a fantanstic app - and built by users!!
My question relates to the Dashboard Plug-In. It seems it always reads True Compass
- can it be set for Magnetic display?
I have my current
on-boad system (Raymarine/C-Map) set to show Magnetic because it then matches (more/less) the ship's compass
at the binnacle.
During my experimenting I have used 2 GPS
units. 1) An old eTrex original - yellow - connected by serial
cable through a USB-serial adaptor. I can see the eTrex NMEA
RMC sentences send TRUE even though the eTrex local display can be set for TRUE or MAG. Whatever the setting of the local display RMC always sends TRUE. 2) A new Globalsat BU-353 USB connected "puck". It sends RMC too and I assume it is TRUE.
Any experienced users have an answer for this?
