How to: add Bluetooth or Aux cable for Mercedes Benz w221 or Mercedes with RCA input 

When you use the three RCA, can you use the phone to transfer the screen, because yellow is for video, right?

Thanks bro, I’ll give it a try

Thanks man, just one question. I find music played via AUX (not through bluetooth adapter, but directly AUX) rather low in volume - which is annoying, I like my music loud. Radio is playing loud just fine. Have you encountered this? Is that sorted thanks to the bluetooth adapter? Many thanks for your feedback and have a great day.

Can you use male aux?

How can I connect my phone to a class Bluetooth 2009 please

Hi What year is the car?
