9.4 Unit Installation
Fabrication of a wiring harness is required. Sound mechanical and electrical methods and practices are
recommended for installation of the GDU 470. Refer to
for wiring considerations, and to
for pinouts.
Connector kits include backshell assemblies. Garmin’s backshell connectors give the installer the ability
to quickly and easily terminate shield grounds at the backshell housing. The instructions needed to
assemble the backshell connector w/Shield Block grounding system are located in
.
Replacement cursor knobs (part number K00-00578-00) for the GDU 470 are available from a Garmin
dealer.

Refer to
and
for outline and installation drawings.
9.6.1 Unit Installation
The GDU 470 is installed by holding the unit flush with the instrument panel and fastening the four 3/32”
hex socket head screws to the panel as shown in
.
9.6.2 Panel Cutout Template
The GDU 470 Nut Plate (115-01725-03) can be used as a template when marking the panel for cutout
(
) (dimensions on the figure are to verify accuracy of printout only). See
complete cutout dimensions. A .dxf version of the drawing is also available for download at
.
9.6.3 Panel Drilling Guide
The GDU 470 Drill Guide (115-01725-04) can be used as a template when marking the panel for cutout
(
Figure 9-6,
dimensions on the figure are to verify accuracy of printout only). See
for complete
dimensions. The drill guide is especially useful when updating from the GDU 37X to the GDU 470, as the
rivet holes on the GDU 470 drill guide and nut plate match the GDU 37X nut plate rivet holes. The drill
guide is attached to the panel using the existing GDU 37X nutplate holes, and is used to make the panel
modifications and drill the new mounting holes. The corners of the existing GDU 37X panel cutout must
be slightly enlarged using the drilling guide as a template. The nut plate is then used to mount the GDU
470 to the updated panel opening.
