Your radio is locked if the CODE display is shown. If the car has just undergone maintenance, had other settings restored, or had the battery replaced, this is a typical occurrence.
You’ll need to enter a code to go beyond the car’s security system in order to open the radio. This code can be found in several places, most notably:
- Look for a database of stereo security codes on the manufacturer’s website.
- in the owner’s guide. Look in the radio/stereo or security sections of the owner’s manual to find the code right away.
- Find out whether your nearby dealership can give you the code or unlock it for you by going there.
The following measures should be used if you are unable to locate the code and the dealership or installation facility was unsuccessful in unlocking it:
- To reset the radio, press and hold the power button for a few minutes.
- Just turn the ignition on, not the engine
- Turn off the radio.
If this doesn’t work right away, hold the power button down for a longer period of time or simultaneously press the power and seek buttons. Hopefully, one of these techniques will get you jamming out once more right away!

Where is the radio code located in the manual?
Look for the Anti-Theft Radio Identification Card in your owner’s manual. There are two sets of numbers in the lower right corner. Your code should be in the top group, which should be shorter and bold.
Why does the radio in my car want a code?
A brief string of numbers known as a car radio code is connected to a security feature found in some head units. By rendering a stolen head unit useless when it is unplugged from the battery, it serves as a deterrent to theft. However, if your battery dies, this feature also activates.
Why does my radio not operate now that my battery is dead?
The anti-theft “feature” that activates if battery power is taken from the radio is the most frequent cause of a car radio ceasing to function after the battery has entirely died. If that happens, all you need to do to get back on track is input the proper auto radio code.
Why doesn’t the radio display on my car work?
The display unit in your automobile can have problems as a result of a bad fuse. If you’re unlucky, a blown fuse will prevent your car stereo from turning on when the ignition is on. A somewhat old but still efficient method of preventing short circuits is the use of fuses.
Additionally, your automobile may have had a fuse installed that was intended to prevent a sudden short circuit from damaging your radio. Your automobile radio display may not function due to a faulty or damaged fuse.
The display unit and the power wire are directly across from this specific fuse. If you replaced the standard stereo with a more modern one, there may be a problem where the aftermarket stereo won’t switch on because of a blown fuse.
So it seems sense that if the fuse blows, the power would cut out. You might be experiencing issues as a result of the fuse blowing while you weren’t there.
Why does my radio not play any music?
Make sure you have an audio source selected, such as the radio, and then verify the radio functions. When using AUX, USB, or BT AUDIO, make sure your device is plugged into the proper input. Check to see if the radio isn’t muted.
4 ohm speakers are intended to be used with Retrosound radios. Please verify the speaker’s impedance.
- Make sure that no wire or lead is connected to a chassis ground by inspecting each set of wires and speaker. This will cause the internal amplifier to be turned off by the radio, which will result in the on but no sound problem.
- Dedicated positive and negative connections from the radio to each speaker connected to the radio are required. (See underneath.)
- By joining speaker wires on a single speaker, radios cannot be bridged. Positive and negative cables from the radio are required for each speaker separately. The speaker wiring must be capped off so it won’t come in contact with any metal or the other speaker if there are just two speakers being used.
You will need to use a multimeter and conduct a continuity test to determine whether the speaker is grounded or shorted.
A continuity test can reveal whether a speaker wire is attached to or in contact with a chassis ground for our purposes.
- Connect your meter’s black lead to the COM port.
- Connect your meter’s red lead to the VmA Port.
- Put the continuity setting on your meter. An indicator that resembles sound waves appears on the majority of meters to identify it.
- By touching the two probes together, you can test your meter; a zero value should be shown and you should hear a beep.
- Disconnect the radio’s main harness from the speaker wire harness. The sets of white, gray, green, and purple are on this white connector.
- Your meter’s black lead should be connected to a chassis ground.
- Test each of the eight (8) wires on the speaker harness of your retrosound radio using the red lead of your meter. (Remember that doing this will test each speaker’s connection to the radio’s wiring.)
- Depending on your meter, you can hear a beep or see continuity between one of the wires and a ground if there is a grounded wire present.
- Retest after fixing the grounded wire.
