Note:
When using the Garmin radome with an expanded network, each network component must be installed according to its installation instructions.
This diagram only shows how a Garmin radome communicates with an expanded network, and does not show the full wiring needs of the other network
components.
Note:
The Garmin radome, Garmin chartplotter, and the other network components must be connected to a power source according to their
installation instructions. This diagram only illustrates the network data connections.
Front of Boat Offset
Depending on the radome installation, it may be necessary to adjust the Front of Boat Offset. If the radome installation requires a 180° offset,
change the Front of Boat Offset to 180° and test the radar. If the Front of Boat Offset needs further adjustment, continue with the procedure below.
Using the bow of the ship, take an optical bearing of a stationary target located within viewable range. Measure the target bearing on the radar.
If the bearing deviation is more than +/- 1°, then do the following to access the Front of Boat Offset from the menu on your chartplotter:
