Thank you for viewing. SANSUI SMS-800BT CD Stereo System with Bluetooth Function After purchase, I confirmed its operation, but I stored it without using it. I replaced the batteries in the remote control and reconfirmed the sound output from CD, FM radio, USB, and Bluetooth (AUX not confirmed). Sound output has also been confirmed using the buttons and knobs on the main unit. Please check the photos and consider purchasing. * I am sorry, but I do not offer price negotiations, so please understand. m(__)m
