Radio issues
 

I have recently bought a used 2014 Hyundai Accent. The radio is not equipped with Bluetooth. When I want to connect my android so that my music comes thru the radio and speakers I can only get one side to work. I have also bought a Bluetooth adapter and nothing just no sound at all. Is audio port comparable to android phones. Note, I have tried my phone with another Accent and it works fine even thou that radio came blutooth ready. Also for some reason I need to connect the USB cable to the phone and plug in the audio cable but like I said before I can only get mono sound. Please advise if anyone else has had this problem and how did you solved it.
