Problem with usb connection

[Android Central Question]

Hello! I installed on my car a pioneer device . First time I connected with iPhone and worked very well. Recently I changed my phone with an Android and now I have the problem . The device is connected via Bluetooth but I don't have sound for my music. It works just for calls . You have any ideas ?
Thank you in advance

Welcome to Android Central! On the phone, go to Settings>Bluetooth and tap the gear icon next to the car stereo listing. Is Media Audio turned on?
