GAD 29) and also the GDL 39/39R will automatically be loaded by the display with no user action

H.3.2 LRU Software Loading Procedure
G3X LRUs (except for GDU displays) connected through the CAN network will automatically receive
software updates from the PFD1 display following a GDU software update. Progress of LRU software
updates can be monitored using the MAIN configuration page. Functionality provided by an LRU will be
unavailable during a software update, therefore all LRU software updates should be allowed to complete
before flight after a GDU software update. The current LRU software versions included with a GDU
software update can be found in the change notes on the software download page.
Problems loading LRU software updates are typically related to CAN network issues. See
Section 2.3.1.3.6
for CAN bus troubleshooting guidance.
