PG500 RMC In signal

Hi: My PG500 is set up to output HDG data to my (non-Furuno) a/pilot and to my MFD12 simultaneously.

But the NMEA0183 Input option for RMC is not utilized. Should it be? What is the purpose/benefit of sending gps info to the PG500?

Thanks
 
Operators manual Pg 4 "When RMC or VTG is input to the sensor, the TRUE LED lights and then true heading is output to other equipment"

Basically the compass uses the magnetic Variation information from the RMC sentence to be able to calculate TRUE (versus Mag) heading. Depending on the install, I normally prefer to let the MFD do the conversion.
 
Thanks Johnny....as I'm getting the PG500 to output magnetic, not True I won't bother with getting an RMC or VTG signal.
