3.6 Downloading and Installing the GRA 5500 Retrofit Installation Tool
GRA 5500 configuration, calibration, diagnostics, and software upgrades are performed (in retrofit/non-
GIFD installations) using a personal computer (installed with Microsoft Windows XP or later) and the
GRA 5500 Retrofit Installation Tool, Garmin part number 006-A0451-00. This tool is also used to assist
in the diagnosis and resolution of asserts found in the GRA 5500 assert log during the installation process
and during post-installation flight operation. The tool is available for download from the Dealer Resource
Center portion of the Garmin website (www.garmin.com). See the accompanying "readme" file in the
tool's installation directory for the latest instructions.
NOTE
A standard USB-A plug to USB-B plug commercial cable (not provided) is required to
interface between a personal computer USB-A receptacle and the GRA 5500 USB-B
receptacle installed in the wiring harness (in retrofit/non-GIFD installations). This
dongle cable is required to use the GRA 5500 Retrofit Installation Tool. Refer to
Figure C-4
for applicable interconnect drawings.
Installation
1. Once downloaded, launch the installation file from the directory in which it is stored (or use the
web browser's download shortcuts).
2. The GRA 5500 Retrofit Installation Tool Setup Wizard will begin.
3. Click "Next" as prompted by the setup wizard, and adjust any settings (e.g. installation directory)
as needed.
4. The last screen of the setup wizard will show "Installation Complete." Click the "Close" button to
close the setup wizard.
NOTE
Depending on the computer's security settings, Windows may prompt the installer to allow
the installation software to make changes to the computer. The installer will need access
to install hardware drivers, program files, and shortcuts. The application may be
uninstalled at any time through the Windows Control Panel.
