 This folder contains a skeleton audio control HAL implementation in Rust to
 demonstrate  how vendor may implement a Rust audio control HAL. To run this
 audio control HAL, include
-`android.hardware.automotive.audiocontrol-V4-rust-service` in your image.
+`android.hardware.automotive.audiocontrol-rust-service` in your image.
 
 This implementation returns `StatusCode::UNKNOWN_ERROR` for all operations
 and does not pass VTS/CTS. Vendor must replace the logic in
