Clarion PU-2358A(C) Sounding

[Kevin28]

Hello,
I bought a old Peugeot 206CC, and there was an other radio inside, but I got the Original Clarion also:
Clarion PU-2358A(C)
Serial No.: CL0xxxxxxxxx

But as I tried to build it in, there was a constant pulsating sound.
A friend told me I have to enter a code, but the display in the car wasn´t asking for a code or something similiar.
Or is it that I just have to enter the code within the buttons without that the radio is asking me?
Is the radio defect, because it´s possible to input a CD and play it but with this pulsating loud sound it´s not possible to hear or sit in the car, like a alarm.

Is there anybody who can help me please?

Thx in advance

Hello guy,

First, yes I´m a technican but normally ´m hardly more focused on Nokia phones by unlocking and als this stuff, more details will follow per PM if you need.
Second is that I was @ my dealer, they told me they can do the radio within 50€, and I´ll don´t pay for that because I know the solution is as simple as unlocking a phone or flashing it.

I just need some help what I can do to keep this radio working without sounding, and I apology if I have done something against the rules.
I have used the search function but found nothing helpfull to my problem I have, because I´m also not quiet sure knowing what this sounding really is, related to an alarm of the radio or because somebody has entered the code wrong before?

And I´m sure I don´t waste anybody´s time here if I have a look at the other threats here.

So please, can you help me?

Nice Regards
