Hi !

Yes, from calc, but code is not correct,
after code enter radio go to safe 9, safe 8 , ...
If leave radio on, ignition on , radio retun to safe 10, I can enter code again.

Any hint to read MCU ?

Regards,
Peter

Radio not should return to its original state safe 10. Entering the code necessary to turn the ignition key.
For reading Motorola need to cut one wire. Upload photo bottom side here

Hi !

Problem solved, in first time I cut on bottom side wire to pin 22, but nothing.
Next cut wire to pin 50, 52, take old PC 100Mhz :) and then communication established with motorola MCU :)
Eeprom content is erased, only on 2 adress is something, others #FF, maybe MCU was secured.
Write another dump, and all OK, radio working :)
All done with polish Motorola interface, old DOS software or Motorola cracker xx, both soft read, write ok)
This radio is very similar to BP Car300, where I cut only wire to pin 22, and make conn with MCU.


Thanx to all for help, problem solved

Peter
