Mercedes w203 Replacing the radio with an original one, but now the changer does

Hello, I have a Mercedes W 203 radio mercedes Becker changer also mercedes A 002 820 62 89 magazine number changer class 1. I broke the radio means it displayed normal radio stations CD changer song number but there was no sound. So I bought a good radio, identical to mine, on the Allegro for a penny. I connected everything as it was with the fiber optic changer. The radio is playing, you hear the sound, the changer lights green, the magazine is pulled out, etc., but when he wants to switch to the changer, he writes NO CD. Does anyone know what the problem could be? I turned off the battery for 20 minutes to reset, so they advised me but nothing helped. Is it true that you need to connect to the original program to connect the radio with the changer because the radio is with a different number? I am asking for HELP, I will only add that when I pull out a new radio and connect my old ones, the changer reacts, you can switch to it without a problem.] Link [/url]

Mercedes Becker radio

There are 10 models - what do you have?

Radio Becker Q08 Model BE 4310 the message is NO CD not much, when I press the cd, the changer pops up NO CD and after 15 minutes on all stations the radio beeps I thought it was a power amplifier that I bought a broken radio. But today I was going on a tour and I only listened to the radio, I did not press the CD or changer and the radio works normally without squeaking, it works perfectly. Only the changer does not work and when I want to switch to it, it is NO CD and after about 15 minutes the radio starts beeping but it does not turn off, only the game and squeaks in the columns. I have to turn off the car, take out the key, light up and the radio goes until I press the CD (i.e. the changer because it starts squeaking)

Recently, it did the same to me as on the old radio, there were stations but there was no sound, but when I pressed the CD or the changer, the track appeared as if the radio saw the changer, but what if the sound was not there, after 15 minutes, the radio started to walk normally, the sound came back but when I pressed the CD the usual NO CD popped up. I do not know what is going on and I was with 3 electricians, they also do not know that you need to connect the radio with the changer through the program.

Do you have BOSE there?

Yes, the Bose sound system. But the speakers are all functional, they were checked for signal. From this radio, what is now, there is no signal coming from the optical fiber because it does not shine, said the electrician. They don't really know what is.

Look for a break in the fiber.

There is a phone module?

Well, let me tell you that the last time the earpiece appeared on the radio and the cable (optical fiber) was not checked, I told them that maybe the cable is short-circuited, maybe it is broken, they said that not okay tomorrow I will unplug the radio and the changer and check it carefully if it is broken somewhere or broken maybe Thank you for the information, let me know.

Hello again, optical fibers pulled out by an electrician and claims that it is completely undamaged. Today again the radio stopped working but the changer started to read but the massacre of such specialists here in Przemyśl did not go, that there is no one to go to. Advice please.

Do you have any other ideas, because once again the radio stops making a sound and the changer is surprised and when the radio starts beeping at each station, I turn off the engine and turn it back on and it's ok I don't really know what's going on, help.
