When the Flight Stream 210 device is powered on or the Flight Stream 510 inserted in the data card slot,
pairing mode will not be enabled until the
Connext Setup
page is opened on the GTN Xi.
The default Flight Stream 210/510 Bluetooth name is “Flight Stream” followed by the three-digit model
number (i.e., “210” or “510”) and then the last four digits of the MAC address (e.g., Flight Stream 210
4000). A pop-up will appear on the GTN Xi screen asking for confirmation of the new Bluetooth pairing.

established with a Bluetooth device, the Flight Stream 210/510 will automatically connect to the Bluetooth
device upon power-up. The Flight Stream may be connected to up to four Bluetooth devices
simultaneously. The Flight Stream 210/510 will also save up to thirteen Bluetooth device pairings.
