E320 new radio no sound
Hello I am new to the board. Very cool there are so many Mercedes knowledgeable people here. I am hoping someone can help.
I have a 99 E320 that I took the stock radio out and replaced it with a pioneer deh-7400mp, cd/mp3 player. The stock system was a radio/cassete player with a BOSE sound system. No NAV or anything else. I pulled the radio, got a adapter wiring harness and plugged it in. The radio seems to work perfectly except I do not get any sound. The wires on the harness and the radio that correspond to the speakers are connected (grey to grey,black-gray to black grey etc) I noticed there was a fiber-optic cable connection in the back of the stock radio, I thought that might be used for steering wheel controls, even though my steering wheel has no controls. My question is how can I get sound out of the radio? Where does the fiber connector go to? Is the fiber connecter used to go to the speakers? Any suggestions for a newbee. thanks Robert |

There a couple of possible problems. #1 the amplifier turn on wire needs to be hooked up. #2 it is hooked up but to the wrong terminal. Check out how you have them hooked up and let me know.

I'll be hornswoggled. The harness docs labeled the blue wire as AMP remote, so I ignored it.
After your reply I tied that to accessory 12v and walla! Sound! Very cool thanks so much for the reply. Man the system sounds so good now, I didnt know the stock speakers could sound so well. Just shows how weak the OEM head unit is. thanks much Robert |
