Hello twinspain,
Technical informations are correct. But somethig is missing.

Why have you no sound ?
It's logic because there are no switching about the audio signals on Input entries..
The radio don't know that it must switch !

A switching signal (5V DC I think) is necessary comming from the external unit you want to connect.
I have to look about witch pin is dedicated for this function.

Hello twinspain,

I think you have the solution in your own message with the second picture.
Actually, I have no Atlanta SQR 49 to make a test, sorry !

Here is the detail of the connector (the top one with 10 Pin)
 
BLAUPUNKT BREMEN OR ATLANTA SQR 49 , AUX IN?? Blaup-Sch-CDC-M1_02aam
 
As you can see, Pin 1 and 2 are the audio signals with ground at Pin 5.
Pin 3 is the switch control. The resistor is not critical, I think 1K Ohm or more.
A switch must be added between that resistor and Pin 6 supplying 12V

It should work !
Tell me if you have a result Cool
