Carletter Cast

Carletter Cast suits drivers who want a larger view of phone apps on a vehicle screen when the car is equipped with CarLetter software. It is designed to work with a CarLetter head unit, so users should confirm support with a brand dealer before installing. The app is not a standalone solution and depends on the in-car CarLetter environment to connect and display content. You can install the Carletter Cast APK and then mirror the apps you already use in everyday driving.

Carletter Cast features

Android screen mirroring on the car display

Carletter Cast mirrors your phone or tablet screen on the vehicle’s central control display. This provides a larger view that matches what appears on your device, which helps you check maps, music lists, or app screens at a glance.

Works only with CarLetter head units

Carletter Cast relies on the CarLetter onboard system that runs on the car’s head unit. The app does not operate by itself and cannot enable mirroring on vehicles that do not include CarLetter support from the manufacturer.

Designed for navigation, music, and daily apps

You can view navigation, music players, and other mobile apps through standard mirroring. Carletter Cast reflects the content currently shown on your device, so layouts and behavior follow the phone’s screen without separate integrations.

Vehicle compatibility should be confirmed

Vehicle brands configure head units differently, so compatibility and menu names can vary. To avoid setup issues, users are advised to check with the dealership that CarLetter is installed and activated before setting up Carletter Cast.

Android focus within the CarLetter ecosystem

Carletter Cast is built for Android devices. If you use an iPhone or rely on CarPlay, that is handled by separate CarLetter solutions and is not part of this Android mirroring app.

Before downloading Carletter Cast

Carletter Cast requires a head unit that runs the CarLetter in-car system. If your vehicle only supports Android Auto or CarPlay and does not include CarLetter, this app will not connect. Users should confirm with their brand dealer that CarLetter is present and enabled on the vehicle to ensure expected behavior.

To keep up with Carletter Cast latest version details or language variants, check official resources from CarLetter. A Chinese build is available on the developer’s website for users who need it. If you look for the Carletter APK latest version, verify that the file matches your device and region and that your vehicle’s CarLetter software is up to date.

How to use Carletter Cast on Android

The steps below outline how to start mirroring with a CarLetter head unit. This applies to Carletter Cast Android users who want to link their phone to the car display. Menu names can vary by vehicle brand, so follow any on-screen prompts from your head unit.

1. Confirm that your vehicle has CarLetter installed and active on the head unit. If unsure, ask your brand dealer to verify support.
2. Install the app on your Android device and open it. When prompted, grant the screen casting and display permissions so the phone can share its screen.
3. On the car display, open the CarLetter interface and select the casting or phone link option. The exact menu or icon name can differ by brand and software version.
4. Launch Carletter Cast on your phone and follow the prompts until the car screen shows your phone display. If mirroring does not start, ensure any required wireless toggles on the head unit are on and that your phone is discoverable as needed.
5. If it will not connect, try removing the previous pairing from the car side and reconnecting from the phone. If wireless still fails and your head unit supports it, begin with a direct USB connection to establish the first link, then switch to wireless later if available.
