ScreenTune Features and Configuration Options
ScreenTune changes a reviewed set of behaviors on a compatible Gen 6 Mazda Connect unit running v74.00.324. The order intake records the vehicle, firmware, wireless CarPlay use, and factory features that must remain available. The installer verifies the exact build before making changes.
Daily-use changes are on by default
Section titled “Daily-use changes are on by default”Turn off individual changes under Features → Customize in the configurator.
| Change | Result |
|---|---|
| Faster screen startup | The test CMU became touch-ready at about 32 seconds instead of about 48 seconds. The benchmark page documents the captures and limitations. |
| Touch while moving | The factory speed lockout no longer disables the touchscreen after the car starts moving. |
| Fewer notices | The startup disclaimer is skipped, and the “Please Check Surroundings For Safety” text is removed from the camera image. |
| Quicker navigation | Pages respond sooner, and menus and lists wrap from the last item to the first. |
| Disable interface beeps | Turns off menu beeps and some notification sounds without changing your car’s warning settings. |
| Reliability work | ScreenTune fixes Mazda’s message-ordering defect, reduces background logging, and increases the interface cache. The message-ordering fix is documented separately. |
Wireless CarPlay startup is included only when selected
Section titled “Wireless CarPlay startup is included only when selected”The intake asks whether the car uses wireless CarPlay. When selected, ScreenTune starts the CMU’s wireless network and CarPlay software sooner, moves that startup work away from the busy processor core, and opens CarPlay when the phone connects.
The test configuration connected wireless CarPlay at about 55 seconds instead of about 71 seconds on a typical cold start. The measured improvement was about 16 seconds typically and up to about 20 seconds on a good boot. Phone handshake time still varies. Wired CarPlay does not use this path. Why ScreenTune is faster explains the mechanism.
Meters is included when selected
Section titled “Meters is included when selected”Meters is a separate Miatafy product delivered inside a compatible ScreenTune build. It adds ten instrument themes and 59 selectable live readings to the factory Mazda Connect screen. It runs on the CMU without a phone, OBD adapter, account, or cloud connection.
Meters is included at no extra charge, and selecting it does not delay checkout. See Getting Started with Meters and the complete data reference.
AA Touch is included when selected
Section titled “AA Touch is included when selected”AA Touch adds tap, swipe, drag, and on-screen keyboard input to Android Auto on the factory Mazda Connect display. It works while parked or moving, and the commander knob, steering-wheel controls, and voice input remain available.
AA Touch is an optional checkbox, included at no extra charge. Android Auto must already work through factory or retrofit hardware; this option does not add Android Auto or turn a wired connection into wireless. Existing customers whose package does not already include AA Touch will receive an updated package by email.
Unused factory software follows the vehicle profile and your choices
Section titled “Unused factory software follows the vehicle profile and your choices”Mazda shipped the same CMU software across cars with different equipment and regional services. ScreenTune builds a vehicle profile from the model, year, market, and trim, then asks about any feature that still needs an owner decision.
| Factory feature | ScreenTune behavior |
|---|---|
| CD, DVD, or factory TV software | Preserved whenever the hardware is present or uncertain. It can stay off only when the reviewed profile confirms that the car does not have the hardware. |
| DAB digital radio | Stays enabled unless you select I don’t use DAB. Turn it off. |
| Built-in SiriusXM | Stays enabled unless you select I don’t use built-in SiriusXM. Turn it off. |
| Mazda maps and compass | Stays enabled unless you select I don’t use Mazda’s maps or compass. Turn them off. CarPlay and Android Auto maps are separate. |
| Aha and dashboard Pandora | Each stays enabled unless you explicitly turn it off. Phone apps, Bluetooth, CarPlay, and Android Auto are separate. |
| Mazda voice commands | Stay enabled unless you turn them off. Siri and the Android phone assistant remain available through CarPlay or Android Auto. |
| Discontinued Stitcher software | Stops loading as part of the reviewed profile. Stitcher’s service ended in 2023. |
Unchecked choices stay enabled. If the profile and the car disagree, the intake records the difference for manual review before the package is delivered.
ScreenTune does not add unselected apps or hardware features
Section titled “ScreenTune does not add unselected apps or hardware features”The current customer product does not include:
- custom boot animations, backgrounds, themes, or accent colors;
- telemetry logging or unselected Mazda Connect apps and input features;
- Wi-Fi access, SSH access, or a video player;
- CarPlay or Android Auto hardware;
- a conversion from wired CarPlay to wireless CarPlay; or
- changes to the engine, transmission, brakes, steering, stability control, airbags, or emissions systems.
CarPlay and Android Auto require compatible factory or retrofit hardware. CarPlay retrofit options explain that separate upgrade. ScreenTune changes the existing screen software only.
The package remains reversible
Section titled “The package remains reversible”REMOVE restores the managed files saved during the first installation and removes active ScreenTune runtime files. That baseline is factory only when the CMU was stock at first installation. See Safety and risk and Install, update, and remove.
