It still requires a code. But the code for Model CM5903 is hardwired inside the radio instead of using an electronic memory chip (EEPROM). What we require is a CLEAR photo of the green circuitboard inside your radio. From this we can find the relevant tags and work out the code for you to enter.

We will send a photo showing the details required on the circuitboard. Keep in touch. It still requires a code. But the code for Model CM5903 is hardwired inside the radio instead of using an electronic memory chip (EEPROM).
