Is there any way to output nema in magentic .
thanks steve
Not really, the NMEA protocol is very specific regarding magnetic vs true headings. Some of the sentences specify both. Is there an underlying issue you are trying to solve that we can help with?

Thanks
Well, I'm not aware of any problems with our NMEA output. The protocol includes true and magnetic data. So not sure what I can do...have you checked with the instrument manufacturer?
