A2DP Volume

Automatically adjusts the media volume on connect and resets it on disconnect.
This is done so that stereo streaming audio can work properly. Intended
primarily for car Bluetooth systems. It can read out text messages using Text To
Speech (TTS) services while you are connected. Each paired Bluetooth device or
virtual device (home dock, car dock, power connection, or headset plug) can be
configured to your liking. There is a
manual on the website.

A secondary feature is the ability to capture location information so you can
find where you left your car. The location can also be automatically captured
when exiting Car Mode on your Android device and read by any app that
understands GPS data.
