Garmin G1000H Pilot's Manual page 345

The G1000H also displays message advisories on the PFD which may indicate a problem with the GDL 59H;
refer to Appendix A for more information.
WORLDWIDE WEATHER IN REVERSIONARY MODE
When the G1000H is operating in Reversionary Mode, only those weather products which can be displayed
on the PFD Inset map will be available for display (see Table 6-4 for a list of weather products and their
associated map availability).
If manual weather data requests were enabled prior to entering Reversionary Mode, no new GFDS weather
data can be retrieved while operating in Reversionary Mode. If automatic weather data requests were enabled
prior to Reversionary Mode operation, the system will continue the automatic data requests in Reversionary
Mode (provided automatic requests have not been inhibited due to a system error).
