NOTE
Sensor and Control Data Sharing Requires
Consistent Software Versions
For complete data sharing between dual AeroNavs,
both units will need to have the same main software
version. If the AeroNavs have different software
versions, then the sensor and control data (e.g.
weather, traffic, fuel, volumes, keyboard
convenience mode, etc) will not be shared between
the AeroNavs.
So, in summary, to have full data sharing between dual panel-
mount AeroNavs, the following rules must be satisfied:

CrossSync must be turned on in both AeroNavs (this is a
maintenance mode setting)

Both AeroNavs must have the same SBAS antenna
configuration

Both AeroNavs must have the same nav database cycle

Both AeroNavs must have the same software version
Independent Data (Dual AeroNav Operations)
The following list of data will never be shared between two
AeroNavs no matter how they are configured:

AeroNav page and tab selection

Map view, range, declutter, and overlay settings

Chart extent box depiction on map

Nav Source selection

Com/Nav settings (e.g. 8.33 vs. 25 kHz spacing) †

Com/Nav frequency selections (therefore no cross-side
tuning or display) †

Nav deviation data (therefore no navigation miscompare
alerts are provided)

Local CAS alerts
