SAGEM AFFA2 Display: Accurate Pinout for Connecting with RENRDW380 Car Radio (GND on Pin 18)

Hi to all (sorry must to write on english),

I have car radio display Sagem AFFA2 and want to connect it with RENRDW380 (for repairing purposes). Here is picture of display and connection diagram.
I downloaded connection diagram and this pinout is not working or it`s bad.

MASA (GND) is not on pin 20, GND is on pin 18! Now I can turn on display but do not have communication with car radio.

Also, C1 connector pinout:

1 DTA
2 CLK
3 MIRQ
4 n/c
5 Radio ON
6 GND


On connection diagram for AFFA2 display pins 2 (CLK) and 3 (MIRQ) are connected together?!

Do You have 100% correct and checked pinout for Sagem AFFA2 display?

Thank You!

So, communication is via 2 pins (different from TUNER LIST displays where communication is via 3 pins). Now is much clearer!

Thank You!

Topic closed!

All is working now, I have communication.
Error in connection diagram is that GND (MASA) is on pin 18 (not on pin 20!).
