ScreenTune vs MZD-AIO for Mazda Connect
Comparison · Gen 6 Mazda Connect
ScreenTune vs MZD-AIO
The deciding factor is which firmware your CMU runs. MZD-AIO targets v55–v70. ScreenTune targets v74.00.324A, the final Gen 6 release. AIO does not run on v74.
The v74 filesystem layout differs from the versions AIO was written against, and pointing AIO at it can leave the system in an inconsistent state. On v74, ScreenTune is the only tested path. On older firmware you intend to keep, AIO is still a capable tool. Check your version under Settings > System > About, or see check firmware.
What each tool is
Section titled “What each tool is”MZD-AIO is an open-source community project from Trevelopment. It opened Gen 6 customization for an entire generation of owners and ran free for years. Development stopped around 2020, so it never gained v74 support and is maintained only by the community now.
ScreenTune is a commercial product from Miatafy built for v74. It installs from USB, applies a fixed set of tested changes, and reverts to stock through the Miatafy app. See how it works.

Where each one fits
Section titled “Where each one fits”MZD-AIO — v55–v70
The right tool if you are on v55–v70 and plan to stay there, you want SSH access or the video player, and you are comfortable troubleshooting community software on your own. Start at mazdatweaks.com and the Trevelopment/MZD-AIO repo.
ScreenTune — v74
The right tool if you are on v74 and AIO is off the table: CarPlay roughly 16–20 seconds sooner and full responsiveness ~16 s sooner every start, not just a few trimmed services, with on-screen telemetry, gauges, and GPS logging in development.
ScreenTune is $79 and covers the full set of changes (touch while driving, disclaimer removal, the performance set, and the UI tweaks) from one prepared USB; on-screen telemetry and logging are in development. For AIO on older firmware, see the Trevelopment/MZD-AIO repo.
Moving from AIO to ScreenTune
Section titled “Moving from AIO to ScreenTune”Do not install ScreenTune on top of an existing AIO install. Both tools modify the same system files using different backup conventions, and stacking them creates conflicts that neither uninstaller can cleanly resolve.
The clean path:
- Reinstall stock firmware to return the CMU to a known state.
- Install ScreenTune on the clean firmware.
See backup and recovery for the reinstall procedure and factory reset vs firmware reinstall for the difference between the two.
Why v74 decides this
Section titled “Why v74 decides this”- v74.00.324A is the final Gen 6 firmware. There will not be another update.
- It carries the best CarPlay stability and the latest security patches. Most drivers are better off on it.
- Dealers push it during service. A routine visit can trigger the update without you asking.
- Rolling back is not supported. Once you are on v74, you are effectively staying there.
- AIO cannot run on v74. That gap is the reason ScreenTune exists.
