Gps source
Just curious, from the new manual pg 16,
SOURCE Sets the GPS source for the SVN display (GNAV1, GPS2, AUTO). The Dynon GPS-250 or GPS-2020 have higher accuracy than an ARINC GPS GNAV1 source.
How does the afs gps250 have higher accuracy than the Avidyne or Garmin ARINC Gnav1 ? Does the ARINC strip away something from the expensive gps?

When you don't have to prove the accuracy (to the FAA level) the device you can more decimals of precision which is the case for the GPS-250. (More here) Compare that to a certified GPS which has to guarantee that every decimal reported is accurate.
The GPS-2020 is brand new technology so it runs much faster then a standard AVTN or NMEA 9600 device.
