You probably have on your car stereo either a single push button that you press to select the audio source (Radio/CD/DVD/Bluetooth) or 4 separate buttons labeled: Radio, DVD, CD, Bluetooth, respectively. Because a sync operation can refer only to a Bluetooth audio source (phone, tablet), your stereo is in now in the source mode for a Bluetooth audio source. Find the button or buttons for the selecting the audio source and select Radio or CD or DVD (you are already on Bluetooth).
