Please could somebody help me with the radio code for serial number: M388956?
The radio is a rds 4000

Thanks,

Dan

0331 is the code


Insert the radio code by repeatedly pressing button 1 until the first
number of the code appears on the display.
Press button 2 until the second number of the code appears in the display.
Repeat the process on buttons 3 & 4 to complete the code.
When the code is entered correctly press button 5 and the radio should unlock.
It works very well for me
