I have a Subaru Impreza 2009 and the two charger ports do not work as aux and there is no aux cable input even though the radio aux.

cannot figure out how to get the aux to work the charger inputs do not register as an aux even when they have the aux cord and there is no headphone jack thing that allows aux even though it's supposed to have aux
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Check the fuses with the auxiliary charging ports to see if they have burned. If the fuse is good, then there is an open or short within the wiring to the charging ports. The radio has an auxiliary wire attached to it to turn on the system. Check all of the wiring with a digital ohm meter to see if there is an open or a short that will cause the port to not operate properly. If you need further assistance with your charger ports not working, then seek out a professional, such as one from Your Mechanic, to help you.

AUX 3.5mm cable car audio input: Just plug the device into the extension port of the Subaru Impreza 2009 factory car stereo, connect it to your favorite MP3 player, iPod, iPhone, Android device or smartphone, and hear the CD quality music right away.
I just got a 2011 Subaru Impreza and tried to connect my iPhone to the car using both USB and the Aux port located in the compartment between the two front seats for music.
Premium and Limited models have a USB and aux jack in the center console.
Integrated Bluetooth Car Interface Subaru Impreza 2009 adds Hands Free Calling and Wireless Audio to the original factory Subaru Impreza 2009 car stereo. The system comes with built-in Bluetooth and microphone.
Initially, they were not standard but rather a feature on aftermarket stereos but around 2009, they became a standard on almost all cars.
Aux inputs connectors are nearly always 3.5mm unbalanced TRS that can accept TRRS. Aux outputs can be either balanced mono or unbalanced stereo. Aux send line outputs sometimes have a single TRS connector which can be wired as balanced mono (rare) or unbalanced stereo (common).
An aux-in (or, to use its unabridged title, auxiliary-in) socket is a 3.5mm jack into which you can wire any device that has a physical headphone connection. It allows you to play your own music in your car without the need for a Bluetooth compatible head unit or an FM radio transmitter.
Locate the AUX port in your car.

The ⅛ jack (or 3.5mm jack) might be inside your arm rest if you can`t find it on your stereo`s face. A good indicator of whether you have an AUX port is if you have an AUX input button next to your AM/FM buttons. If you have an AUX port, you can purchase an AUX cord from any retailer.

Fortunately, there are several ways to listen to your favorite music from your phone in your car even if you don`t have an aux or Bluetooth connection. These include using an FM radio transmitter, a USB connection, Apple CarPlay, a Cassette adapter, an SD card, a 30-pin adapter, as well a new deck.

ANSWER : Check the fuses with the auxiliary charging ports to see if they have burned. If the fuse is good, then there is an open or short within the wiring to the charging ports. The radio has an auxiliary wire attached to it to turn on the system.

Aux button on my radio
ANSWER : If the vehicle is equipped with an aux jack, it would be located in the center console bin, on the bottom towards the front. Later models have the jack located just in front of the shifter on the lower dash below the climate controls. If no aux jack is present, your local Ford dealer parts department may still be able to order an installation kit. If it is no longer available from Ford, a reputable stereo installation shop should be able to install one for you.

My dash board don’t work my front light work when I change my light into high beam and my back window won’t go down
ANSWER : As unfortunate as it is, your vehicle would be considered flood damaged. Diagnosing electrical problems in a flood damaged vehicle is nearly impossible. This would take many hours or even days to determine which wiring harnesses and circuits have been affected. Then nearly all of the wiring under the dash would likely require replacement as well as many sensors and switches. On a BMW vehicle, the amount of wires and switches are likely more than that of a lower end vehicle. Due to the inefficiency in cost, you would likely be able to purchase another BMW like yours for less than what it would cost to fix your car. Many insurance companies would consider this type of damage to total out the vehicle unfortuantely.

Aux input is not working in the radio
ANSWER : You will need to visit a Volkswagen workshop to have the service performed. Their equipment will be able to determine whether the fault has to do with coding, or a malfunction in the radio itself. They will be best equipped to replace the faulted components.

Windshield wipers stopped working. They’ll suddenly stop working then suddenly start working again. Has been happening for a week.
ANSWER : The problem you are describing likely stems from an intermittent electrical fault in the wiper circuit. The windshield wiper system uses a small electric motor to move the wiper arms that you see on the windshield. That electric motor is controlled through a switch, relay, fuse, and wiring. One, or more, of those electrical components has failed although it is also possible that the mechanical arms are binding (seized, if the lubricant has dried out) thus causing the electric circuit to the motor to overload. Regardless of the underlying fault, if you request a non functioning wiper diagnostic/repair, the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Car radio will not pick up radio stations.
ANSWER : There are multiple issues that could cause a radio to not pick up an AM / FM signal. In most cases it’s due to faulty wiring, a loose ground wire or the wiring running to and from the antenna. However, it’s also possible that an internal component inside the radio such as an electrical relay has been damaged. It might be best to purchase a new tuner; as diagnosing and fixing this issue would most likely be more expensive than the cost of buying and installing a new one.

I have a factory Bose radio in my 2009 Mazda RX-8. The radio works but I cannot heary any sound. What could be the issue?
ANSWER : Hi There,
It sounds like you may have some faulty wiring running from the stereo to the speakers. This is somewhat common and can happen for many different reasons. Often times, when the wiring is faulty producing a bad connection, you may hear the sound coming from the speakers intermittently as you describe. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.

Radio Fault
ANSWER : Hi Kritesh. It sounds like the stereo amplifier in your vehicle has failed internally, lost power, lost ground, or lost signal from the radio. Perform a quick check of the radio functions; change stations, adjust volume, etc… If all of these are showing proper changes on screen, then the problem definitely lies in the amplifier area. Using an electrical wiring diagram, locate the power source and ground for the amplifier and check with a digital volt ohm meter; repair as necessary. Based on my experience with Toyota & Lexus, I’ve found that the amplifier fails much more often than the radio. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. If available in your arear, Your Mechanic has several available technicians that can assist you with a radio has no sound inspection.
