Already Own a DJI O4 Air Unit Pro? Choose the Right Listing
Check video-system inclusion first
If you already own a DJI O4 Air Unit Pro and plan to install it, compare a listing that explicitly excludes that system. Each model also has a separate listing with the video system included.
| Model | Excludes DJI O4 Pro | Includes DJI O4 Pro |
|---|---|---|
| XI20 Pro | Without O4 Pro | With O4 Pro |
| XI25 Pro | Without O4 | With O4 Pro |
| XI35 Pro | Without O4 Pro | With O4 Pro |
Then check the rest of the build
Choose the correct power configuration and receiver. PNP includes no receiver; you must install your own compatible receiver. On XI25 Pro, choose the battery connector too. Having the video system already does not establish that your radio, goggles, wiring, mounts or firmware will work without further checks.
Read the current product title, description and selected configuration together. Some existing URLs contain historical wording, so the URL text alone is not a reliable description of the included system.
This guide covers the listings described for O4 Pro. It does not establish that every DJI O4 or older DJI video unit can be substituted. If your exact unit or hardware revision differs, confirm it before buying the installation parts.
