That is what I was able to read from 24L04, per this schematic that is the installer memory / eeprom on the KDC-W7531Y
https://drive.google.com/open?id=1o2akYm2Z8nTtPUTMMDnhdNGoCoEh-TmT

The weird thing is that when I tried to power on the radio after removing the EEPROM from the board it was still asking for code and wrong code count was at 4, everything I read about getting the code from EEPROM on this model said that without the EEPROM the radio should work without asking for code, but shutdown / require power reset after 30 minutes.

I've been going trough the repair manual linked in the post again and I can't see anything else that should be the EEPROM IC other than the IC I already removed from the board...

Many thanks for your help!
