A Mercedes-Benz ML320 radio code is a four-digit security code that is used to unlock the radio unit in the car. If the code is forgotten or lost, it can be obtained from the dealer.
The code is entered using the radio’s preset buttons. The first two digits are entered using the left and right arrow buttons, and the second two digits are entered using the up and down arrow buttons.
If the code is entered incorrectly, the radio will beep three times and will not unlock. The code can be entered up to three times before the radio will go into lockout mode. In lockout mode, the radio will not be able to be turned on or off, and the only way to reset it is to take it to the dealer.

Why does my radio not work after changing battery?
A car’s radio relies on electrical power to function. When the car’s battery dies, the radio will not work. If the car’s battery is replaced, the radio may not work. There are several reasons why the radio may not work after the battery is replaced.
The radio may not work because the new battery is not fully charged. When the battery is installed, the car’s electrical system will try to charge it. If the radio is turned on before the battery is fully charged, it may not work. The radio may also not work if the new battery is not the correct type for the car.
The radio may not work because the electrical system is not properly grounded. The battery ground wire must be connected to the car’s chassis ground to provide a path for the electrical current. If the ground is not properly connected, the radio will not work.
The radio may not work because the electrical system is overloaded. When the battery is replaced, the electrical system will try to draw more current than the old battery could provide. This may cause the electrical system to overload, which will prevent the radio from working.
The radio may not work because the fuse is blown. The fuse protects the electrical system from overload. If the fuse is blown, the radio will not work.
The radio may not work because the wiring is defective. The wiring in the car may not be able to handle the amount of current the radio requires. This can cause the wiring to overheat and melt, which will prevent the radio from working.
The radio may not work because the antenna is not connected properly. The antenna must be connected to the radio to receive a signal. If the antenna is not connected properly, the radio will not work.
The radio may not work because the antenna is damaged. The antenna may be bent or broken, which will prevent it from picking up a signal.
The radio may not work because the head unit is defective. The head unit is the part of the radio that contains the electronics. If the head unit is defective, the radio will not work.
If the radio does not work after the battery is replaced, there are several things that can be done to troubleshoot the problem. The first step is to check the battery and the car’s electrical system to make sure they are both properly connected. The next step is to check the fuse to see if it is blown. If the fuse is not blown, the next step is to check the wiring to make sure it is not overloaded. If the wiring is overloaded, it may need to be replaced.
If the radio still does not work, the antenna may need to be checked. The antenna may be bent or broken, which will prevent it from picking up a signal. The head unit may also be defective, which will prevent the radio from working. If the head unit is defective, it will need to be replaced.
Where is the radio code on a owners manual?
Most car radios have a security code to prevent unauthorized use. This code is typically found in the car owner’s manual. If you have lost your owner’s manual, or if the code is not printed in your manual, you may be able to find the code on the radio itself.
On most radios, the security code is a four-digit number. Some radios may require a six-digit code. The code is usually entered by pressing a sequence of buttons on the radio. The code may also be entered by using the keypad on the car’s dashboard.
If you cannot find the code on the radio or in the owner’s manual, you may be able to contact the manufacturer of the radio for assistance.
