This update adds keyboard text input, full screen, more CarPlay resolutions, and speed units, and simplifies setup.
What's changed
- Simpler setup. The installer includes the MFi files, so you no longer need to add a certificate and key manually.
- Keyboard text input. Type in CarPlay fields using the iPhone's layout; letter shortcuts pause while typing.
Keyboard → Text input → Type in CarPlay is on by default; reconnect after changing it. Shift, Caps Lock,
Home/End, and text-selection shortcuts do not currently work in the tested CarPlay fields. - Full screen with F. Toggle full screen independently for the focused CarPlay or AltScreen window; press F
again to restore its previous size and position. - More resolutions. Added 1080×1080, 2560×1080 (2.5K Wide), and 2560×1440 (2.5K). Reconnect to apply.
- Smaller windows. CarPlay streams wider than 1280 pixels can fit a window 1280 screen pixels wide, regardless
of Windows display scaling. Aspect ratio locking keeps the picture's proportions. - km/h or mph. GPS → Speed units immediately changes the scale, needle, central reading, and GPS speed
display. The imperial scale goes to 180 mph, with finer steps at lower speeds. - Steering input by default. The wheel follows steering input, with a separate heading compass in the tachometer.
Heading mode remains available, and existing saved wheel modes are preserved.
