Hi, I just installed a Sony cdxr3000 head unit in my 420SEL, the radio works fine, better sounding than the Becker I removed but for some reason the CD player gives no sound output at all. The CD is running and I have tried 2 different CD's in case 1 was faulty. Before I purchased the car someone had installed a sony 10 CD changer that worked through the becker radio with a controler mounted below the radio itself. I have removed all of the components but still no tunes. Any advice is welcomed.
