===Thread external GNSS and GPRS antennas (if needed according to device model).===

If your device uses external antennas, thread them through the dashboard and fasten them in place. The external GNSS antenna reciever should be as close the the windshield as possible, obstructed by the least amount of metal. Likewise, device with internal antennas should be also placed as close to the windshield as possible.
