Resolving "NAV ACCUR UPGRAD" and Missing Heading Map Issues on A321 for MSFS 2020 (Xbox)

It's certainly frustrating when you're eager to hit the skies and encounter such hiccups. But fret not! Let's try to diagnose the issue and get you soaring in the A321.

1. Initialization Sequence: First, ensure you're following the correct initialization sequence for the A321. Unlike some smaller aircraft, airliners require a systematic approach to start-up.
2. Database Update: The message "NAV ACCUR UPGRAD" is indicative of a navigation database that may be outdated or not correctly initialized. Typically, this is encountered when the flight management system (FMS) doesn't have the recent navigational data. Do check if there have been any updates to MSFS 2020 recently and ensure you've installed them. Moreover, some third-party mods or liveries can sometimes interfere with default aircraft systems. If you have any, consider disabling them temporarily to check.
3. Graphic Settings: While on PC, altering graphic settings often resolves display issues; on Xbox, this is less common. However, it's worth checking if a reset of your graphic settings can make a difference.
4. Reinstall Aircraft: This may sound a bit drastic, but sometimes the files associated with specific aircraft can become corrupted or not properly installed. Try uninstalling just the A321 and then reinstalling it. It can potentially rectify any display issues.
5. User Profiles: Occasionally, the user profile can have some glitches. You might want to check if other aircraft have similar issues or if the problem is localized to the A321. If other aircraft work perfectly fine, it further indicates that the problem might be with the A321 file itself.
6. Consult the Manuals: I'd recommend having a glance over the aircraft's operational manual if it's available in-game. Sometimes, the solutions lie in understanding the aircraft's intricate systems.

Lastly, while I understand the allure of flying the A321, if the issue persists, don't give up entirely on your aviation aspirations. There are a plethora of other incredible aircraft in MSFS 2020 to explore and master while this issue gets sorted. And always remember, the flight sim community is vast and supportive. If you ever need assistance, we're here to help!

Safe skies and happy landings!

Stephen — if you’re seeing “NAV ACCUR UPGRAD” and the ND is basically blank (or the PFD/ND are white with just the runway), that’s usually the Airbus telling you it doesn’t currently have a valid position / nav solution yet. On Xbox that’s most often down to the sim not loading in a good GPS position, a bad/corrupt content install for that aircraft, or occasionally the online/data side not actually feeding it.

Here’s what I’d try, in order, keeping it simple and “Xbox-safe”:

1) Force a clean cold start and let it sit for a minute

1. Load the A321 at a gate/stand (not “on runway”).
2. After the flight loads, don’t touch anything for ~60 seconds.
3. Then apply ground power (or start the APU) and bring the screens up.

Sometimes the nav solution catches up only after the aircraft is properly powered and the sim has finished streaming the initial position.

2) Check the sim’s Online/Data is actually ON
If online functionality/data streaming gets toggled off (or you’re offline without realizing), some aircraft get weird about nav initialization.

1. Verify you’re logged in and the sim is in Online mode.
2. Make sure Data/online services aren’t disabled.

(Names of the menu items vary a bit by sim update, but you’re basically looking for the “online/data” options and confirming they’re enabled.)

3) Delete and reinstall just the A321 package
Since your 737 is fine, I’m leaning toward the A321 content being borked on install.

1. Go into Content Manager.
2. Find the A321 package you’re using.
3. Delete it.
4. Fully restart MSFS (important on Xbox).
5. Re-download/install the A321 again.

4) Remove anything extra tied to that aircraft
If you’ve installed any A321 liveries, enhancement packs, or anything “Airbus related” from the Marketplace, temporarily remove/disable those and test the base aircraft first. On Xbox you can’t manage a Community folder like PC, so Marketplace items are the usual culprit here.

5) Try a different airport/region as a test
This sounds odd, but it’s a good sanity check:

1. Spawn at a different airport (preferably a default airport, not a heavy add-on scenery).
2. Pick clear weather / daytime.

If it works at some airports and not others, that points away from the aircraft itself and more toward a scenery/data conflict.

A couple of quick questions so I don’t send you in circles

• Which exact A321 is this on Xbox (the default Airbus A320neo variant, an “A321” from the Marketplace, or an Airbus/A321 included with a specific package)? The exact product matters a lot.
• Does the message appear immediately on spawn, or only after you power up the aircraft?
• Are you starting Cold & Dark, at a gate with engines running, or “on runway”?
• Do you have any Airbus-related Marketplace add-ons/liveries installed?

Answer those and I’ll tailor the next steps to your specific A321, because the fixes can differ depending on which one you’re actually flying.
