I have a E97 MFD with external GPS150 from Digital Yacht connected to NMEA port 1 at 38400 Bauds. Sentences send by GPS are :
GGA/GLL/RMC/GSV/GSA/VTG/ZD at 1 Hz rate.
Internal GPS is disabled.
GPS works well. I can see its status with HDOP equals to 0.6.
My problem is the COG/SOG filter is unavailable (stay grey). I cannot select the level of this filter. So the course vector changes a lot with boat oscillations.
With internal GPS, this menu is available.
Why COG/SOG filter is unavailable with external GPS ?
