Thank You Dave,

I know that this is improbable, but maybe garmin had put this covert
function only for some selected guys to test it; the new release 3.20
included the setup NMEA speed (high speed/normal speed) but do not say
what speed is... And if AIS and the NASA engine is having this fast
and large aceptance, being selled by several others software and
hardware makers, why not adopt it too, and make a litlle
software/firmware modification to support it? And pheraps, sell it
with garmin logo too, after a period of test?

Best regards and thank you again.
