Can you post dump from old display and radio dump (Radio will need unregistering also)
Also verify new display dump, data looks wrong

There is data missing in this eeprom from your new display, did you buy new or second hand? also did they alter it?
Also you read the wrong chip in the radio, read the chip in the LOWER part.... (See Picture)

Thanks for the info. The contents of the eproma as in your figure 24c64.
I bought the display used and I see that the eprom is not complete, thank you for the information and the desire to help!

Use this dump in your radio, then re-read your new display...
