3. Once the GoBook is properly aligned on the vehicle dock, push the locking
mechanism in (1) to secure it. This locks the pin in place on the underside of the
GoBook and also engages the mounting guides.
4. One end of the USB data cable comes attached to the vehicle dock; attach the other
end to the USB port on the MC3.
The USB cable is connected to the dock at the factory and is secured with
a cable tie. DO NOT remove this cable tie or unplug the USB cable from
the dock. The cable tie helps ensure a secure connection and should never
be disconnected. The cable tie also ensures that the correct COM port is
used for GPS communications with the Mobile Interface software. Using
a different USB port will prevent the MC3 radio from communicating
properly with the software.
5. Connect the antennas and power cables for the MC3 as described earlier in this
document.
