4. Install the six mounting screws into the bezel of the GDU 620.
NOTE: The installation configuration settings are stored in the
configuration module and will be retained when the GDU 620
is replaced with a new unit. User settings, such as map
orientation preferences, are stored internally and will be lost
when the GDU 620 is replaced with a new unit.
Original GDU 620 is Reinstalled
If the original GDU 620 is reinstalled, then no software loading is required. This does
not include units that were returned for repair as their software and configuration files
are deleted during the repair process. No configuration is required.
New, Repaired or Exchange GDU 620 is Installed
If a new, repaired, or exchange GDU 620 unit is installed, then software must be
loaded. No configuration is required
.
NOTE: Upon first power-up after installing a new GDU 620, it is normal
to see a series of “LOADING…” messages appear on the screen.
These messages indicate that the GDU 620 is updating its
configuration settings from the configuration module.
Refer to Section 5 of the G500H STC Installation Manual for the GDU 620 Software
Loading procedure (5.4.1), followed by the Manifest Configuration (5.5.5) and the
Configuration Module Update (5.5.12).
GDU 620 Configuration Module is Replaced
If the GDU 620 Configuration Module is replaced, the GDU 620 will update the
configuration module from its internally-stored settings when the UPDT CFG soft key is
pressed. If the GDU 620 is replaced at the same time as the Configuration Module, then
the System Setup will need to be performed per Section 5.5 of the G500H STC
Installation Manual.
