Actually the Brookhouse iMux converts the SeaTalk to NMEA-0183 and then iNavX processes the NMEA-0183. I would suspect the error is occurring in that translation process.
iNavX by default will use HDG instead of COG to orient the position icon. So it may be that HDG is incorrect from SeaTalk to NMEA-0183. Do you see HDG, HDT or HDM in the Instruments view or banner? If so recommend you try turning off the "HDG", "HDM", and "HDT" in the "Instruments" view and see if this fixes the orientation problem. Also toggle the "LinK" button in the iNavX TCP/IP NMEA Client as this resets the values (COG, HDG, SOG, etc.). Lastly, make sure "Location Services" is set to "OFF" in the iNavX TCP/IP NMEA Client, so iNavX knows to use the NMEA-0183 from the iMux instead of the built in GPS receiver.
This is the first ever I have heard of COG being incorrect from the Brookhouse iMux.
