TDS Sim Software has updated their GTN 750Xi add-on for Microsoft Flight Simulator 2024 and X-Plane. The update adds crossfill between the two units, allowing them to talk to each other and exchange data.

Contrary to popular belief, Garmin’s crossfill function does not only synchronize the active flight plan between two units; it also crosses over fourteen items, such as the flight plan catalog, user waypoints, user-defined frequencies, missed approach acknowledgment, nearest airport criteria, CDI scale, and more.

Their crossfill implementation fully replicates the real unit’s behavior, using the same protocols as in real life, ensuring ultimate immersion and fidelity. 

‍

For crossfill to work, one must use an aircraft with two GTN units, be it two 750Xi, one 750Xi and a 650Xi, two 650Xis, and so on. It’s also possible to turn it off if the user wants individual flight plans on each.

‍

To get the functionality working, you should be on the Trainer’s V20.42 version or higher, 1.3.0.0 or higher of the TDN Pro for MSFS 2024, and 1.0.0.4 or higher for X-Plane.

‍

Furthermore, the GTN 750Xi/650Xi is now available in select default MSFS 2024 airplanes, as part of Microsoft Flight Simulator 2024’s SimAttachments feature. Thanks to a mod created by one of their community members, their GPS unit canm now be part of the default Cessna 185 Skywagon, Cessna 404 Titan, and also on the Cessna 172 Skyhawk Classic.

‍

Work is underway to support even more default aircraft in the future: DA40, PC6 Gauge version, DV20, C152, Twin Otter, C207, V35B Bonanza, and H125.
