Not Supported Yet

ScreenTune targets one specific platform: a factory Gen 6 Mazda Connect CMU running firmware v74.00.324A, North American build. If your car sits outside that, this page tells you exactly why, and what (if anything) moves you back inside the line. Some of these are a dealer visit away; some are hardware that will never run our software. We say which is which.

Older firmware than v74.00.324A

Cars still on 55.x, 59.x, 70.x, or an earlier 74.x build aren’t purchase-ready, but they’re usually the easiest fix on this page. The CMU hardware is the same Gen 6 unit; it just needs to be brought up to the supported version. Miatafy does not distribute Mazda firmware — those files come from Mazda, region-matched to your VIN.

Path in: Getting to v74.00.324A walks through the dealer update request, how to avoid the maps/Gracenote mixups that trip up the update, and what to verify when it’s done. Confirm your version first at check firmware.

Firmware v74.00.331

Close, but not the same build. ScreenTune is validated against v74.00.324A specifically; the 331 update can shift file paths, service behavior, and recovery assumptions enough that nothing we’ve tested on 324A is guaranteed on it. We don’t ship modifications we haven’t verified against the exact firmware they run on.

Path in: No clean one today. Don’t roll back unless a region-correct package and a working recovery path are both confirmed — a half-finished rollback is how a head unit ends up bricked. Services can review your situation and may recommend doing nothing for now.

Gen 7 and newer Mazdas

The line that matters runs through the CMU, not the badge. These cars shipped with the next-generation Mazda Connect platform — different hardware, different OS, different software architecture:

2019+ Mazda3
2021+ CX-5 and CX-9 (North America)
CX-30, CX-50, CX-60, CX-70, CX-80, CX-90
2024+ MX-5 (ND3)
Any car with the wide landscape display and the rotary-only, no-touch-while-driving UI

There is no firmware update that converts one platform into the other. ScreenTune does not run on these and there’s no timeline that changes that — it’s a hardware difference, not a missing feature.

Path in: None. If you’re cross-shopping, Gen 6 vs Gen 7 explains what actually changed, and what changed with the ND3 covers the 2024+ Miata specifically.

Wrong-region firmware

ScreenTune is confirmed on North American builds. European, Japanese, Australian, and other regional firmware can carry different file structures, locale handling, and update paths, so a NA-validated install isn’t safe to assume on them.

Path in: Possible after individual assessment. See firmware region codes to identify your build, then contact services for manual review. Some regions are supportable; some aren’t.

Unknown prior modification history

If the CMU has already been through AIO Tweaks, MZD-AIO-TI, or other community modification tools, its file state may not match the baseline ScreenTune expects. That mismatch is a common cause of failed installs and odd post-install behavior.

Path in: Contact services for manual review. A clean firmware reinstall through Mazda’s official process is sometimes the right reset before proceeding.

Wireless CarPlay you can’t account for

Some CarPlay retrofit kits and wireless adapters sit between you and the CMU in ways that can collide with ScreenTune changes. If you don’t know whether your CarPlay is factory, a retrofit, or a dongle, that’s worth resolving before you buy.

Path in: Run the compatibility intake with photos of your CarPlay setup. The review tells you whether your configuration is clear.

Where you stand

Situation	Path in
Older than v74.00.324A	Dealer/firmware update to v74, then compatibility check
Firmware v74.00.331	Wait; services review before any rollback
Gen 7 / newer platform	Not supported, no timeline (hardware difference)
Wrong-region firmware	Manual review via services
Unknown mod history	Manual review, possible clean firmware reinstall
Uncertain wireless CarPlay	Compatibility intake with photos
