2 things about the sat screen:

-The SVee6 in NMEA mode as factory doesn't send sat info. Sending a TSIP packet to it can turn on additional sentences. But... how do we decide something is a SVee6/SVee8Plus so we can send the TSIP?
-The Magellan I have seems to output WAAS as pseudo-satellites numbered e.g. "122". Probably the right answer is to drop satellites>99?
