36.2 Return to Service Information
These return to service procedures are intended to verify the serviceability of the appliance only. These
tests alone do not verify or otherwise validate the airworthiness of the installation.
36.2.1 GDU 37X/GDU 4XX
36.2.1.1 Original GDU is Reinstalled
No software or configuration loading is required if the original GDU is reinstalled. Continue to Section
36.2.2.
36.2.1.2 Original GDU(s) Installed in a Different Position
No software or configuration loading is required if the GDU is installed in a different location. Continue to
Section 36.2.2.
36.2.1.3 New GDU(s) Installed
If a new GDU is installed (new serial number), verify the correct software version on the MAIN page
(GDU 37X) or on the System Information page (GDU 4XX) in configuration mode. Additionally verify
that all installed displays have the same software version, as well as NavData, terrain, and obstacle
databases. If the correct software version is not installed, update the displays to the current G3X system
software available on the web. No configuration is required if the configuration module is still operational.

36.2.1.4 New GDU (PFD) Configuration Module Installed
Ensure that a new configuration module is obtained for the replacement installation. If a new
configuration module is installed and no change is made to the PFD, the PFD will write the required
configuration information to the configuration module. If the PFD and the configuration module are both
replaced, the system will need to be configured (
for GDU 37X and
for GDU 4XX).
NOTE
Do not use a used GDU configuration module as a replacement. Data that may reside on
the used configuration module may cause system configuration errors.
