Hello, I have an Audi A4 Quattro 1.8T 2000
and I decided to remove the Symphony radio from it
as I wanted to install my own Sound System in it with an Amplifier.

Now here is my Problem , I suceeded connection all Speakers
and Tweeter to my new Sony MEX-BT2900 Radio but there is still the Antenna
Wire left to connect cause atm I do not have access to FM via my Sony MEX-BT2900

I have no idea what wire I have to connect to the Sony MEX-BT2900 Radio
to make the FM work, I heard there were 2 Antenna Wire connected to the original Symphony Radio so I am wondering...

Hope someone Can help me cause I would really love to get FM on my new Radio!!

Here's the back of my radio

 

Would be great if someone can answer also..
