I bought one 10.25 Road Top Android Radio for my w212. I'm having difficult with the installation of the radio. I can connect my phone, I could see everything, the only problem is with the audio. NO AUDIO and I can't see my radio. Visiting some cars audio shops no one can help me. I found one that said to me that the problem is that my car is wired with optic fiber and the connector of the new radio is not with optic fiber. The guy said to me that he has to do a bridge to get the sound. It is true? Or there is another way to connect the radio? Please help me.

When I installed my system the thing I had to do was remove the optical cable from the original connector and put it on the new connector.

Hard to explain but the following post shows what you have to do. Looking at the Road Top wiring it appears the same so I am guessing you need to do the same thing.

It's step 7

Any pro and cons for 10.25 Road Top Android Radio for w212? I want to get carplay but wonder if any existing functionality such as radio, surround camera would be impacted.

It is no easy to connect. Must be an experienced car audio technician to do it. I am looking yet for that person. No one want to work with Mercedes.

I installed on my 2014. Everything should be plug and play. Check to make sure the unit they sent is compatible with your head unit. After install I was able to connect wirelessly or wired. The only issue I am having is using the steering wheel controls since the unit uses the aux. I saw you also posted about the back up camera. Make sure you follow the instructions. There are also install videos on you tube

Thanks!

When I did mine I initially forgot to remove the fiber from the original connection and move it to the jumper harness. So that the fiber cables still plug into the original head unit.
