Default NMEA V2.3 sentence question

Does anyone know if the format for the GPRMC sentence has changed from NMEA version 1.5 to version 2.3? Specifically, did the speed format change? Ya I know, geek talk, but one little change can take legacy instruments out of the loop.

I'm looking at a Garmin 2010 installation manual, and I don't see where you can dumb down the NMEA from 2.3 to 1.5. I installed a 2006 yesterday, and everything is listening except the Standard Horizon repeater and the Yamaha engine management system. Gonna have to whip out the laptop...

Thanks,

Kurt
