I write this little gadget beacuse when turn off my bt car audio I forget to pause music before and sound will be rerouted to internal speaker of device. Also when drive my car, if radio station transmit bad music I switch on bt audio and to prevent distracttions is comfortable music auto play if connected without divert attention of drive.
