Code for Volvo CR-603

[Tuunikala]

Hi guys!
I am in terrible need. Bought myself a 91 Volvo 940GL, and it has the original stereo. But, it doesn't work.
So, I'd really like a code for it.
Itī's a Volvo CR-603
The data I found on the top:
VOLVO
1373073-1
4980 9006
Japan
SERIAL NO. 6113490858
VO8580 A6148060B
If you guys can help me, it will be much appreciated!

These older Volvo radios cannot be decoded using the Serial Number
