AudioBT Plus is a free Android application designed to enhance the functionality of Bluetooth audio systems in vehicles. This app allows users to hear GPS navigation instructions and text message notifications through their car speakers or Bluetooth headsets while still enjoying their favorite music. By utilizing the SCO/HFP profile, AudioBT Plus routes audio messages as if they were incoming phone calls, ensuring that important notifications are never missed. The app supports various GPS applications, including Google Maps, Waze, and TomTom, offering a seamless experience for drivers.

One of the key features of AudioBT Plus is its ability to automatically switch audio channels, allowing users to receive notifications without interrupting their music. Additionally, it includes an embedded Xposed module for adjusting audio delays to prevent message clipping. However, the free version has limitations, such as stopping audio routing after five messages and not reading text content in notifications. Overall, AudioBT Plus is a practical tool for improving in-car communication while maintaining an enjoyable audio experience.
