To unlock the Smart radio, you need to disassemble the device to read the serial number written on the sticker inside: once you have the serial number, you must enter it into specific applications to obtain the unlock code. This code should be entered by pressing the number 1 as many times as the first digit, the number 2 as many times as the second digit, and so on. After all the numbers have been entered, press the CD button located on the left side of the radio to confirm the entry and unlock the device.
