Have tried setting cmaps config.exe - "nmea config tab" to gps-com4-RMC and numerous other different combinations but on opening cmap no lat/long is displayed, if I unplug com port then try to open cmap says unable to open port so cmap is seeing the port and I know the data in above format is being input to com port (com port settings are correct ie baud at 4800,8,1 etc). Ready to jump overboard, any help greatly appreciated.
