3 | Mounting the NAV-900 Guidance Controller
NAV-900 Guidance Controller Installation Instructions | 17
Orientation of the guidance controller
The presence of the Inertial Measurement Device (IMD) requires that the device is installed rigidly with
the orientation of the guidance controller being specified in reference to the top/front of the vehicle.
A neutral 0°, 0°, 0° (Roll, Pitch, Yaw) orientation is required, with the dome up and the connectors facing
backwards toward the rear of the tractor.
Mounting options
1. VHB double-sided tape mounting (see page 19).
NOTE – VHB mounting is not recommended for high-precision auto guidance installations and
should be used as the last option; a more rigid fixed mount option is recommended as some cabs
can have flexibility in their structure. For high performance, choose from one of our more rigid
factory mount adapters or spar mount options. See
Optional accessories for mounting, page 9.
