A frustrating and common problem for many drivers is a car stereo system that frequently switches between the aux and radio. This issue could occur while playing music from an external device, like a phone or MP3 player, or car stereo system with the aux audio input on the car’s audio system.

Why Car radio keeps switching from Bluetooth to radio? Possible reasons include loose connections, frayed cables, interference from other electrical devices, and faulty audio jack or Bluetooth receiver.

Stay with us; this article looks at potential reasons for car aux radio issues and various solutions to this problem.

Causes Of Car Radio Switching From AUX To Radio:

Here are some possible causes of car radio switching from AUX to the radio.

1. Loose Connections:

Why does my aux keep switching to the radio? Loose connections are a significant reason a car stereo system switches from radio to aux. You likely have a loose connection inside the radio head or control panel. Many things can contribute to this issue, like a faulty Auxiliary cable or a loose connection between the aux port and the car’s audio system. Most likely if the socket is loose the contact connection or the wiring is connected to it.

In some instances, if the connection drops, the radio may revert to radio mode, stopping the music from playing.

2. Radio Interference:

Why does my aux keep switching to radio? Radio interference is another potential cause of the issue. The automobile radio switches from AUX to radio mode when the antenna picks up signals from other radio stations or devices.

While driving in locations with weak radio signals or close to electronic devices that produce electromagnetic waves, such as cellphones and laptops, this issue is more likely to occur.

3. Damaged AUX Cable:

Why does my aux keep cutting out? A broken AUX cable may be caused if the car radio repeatedly switches between radio and auxiliary modes. Wear and tear, accidental harm, or exposure to excessively high or low temperatures are all potential causes.

When the RCA cable is pushed or roughed up, an intermittent connection caused by a damaged Auxiliary cable may cause the radio to switch to radio mode.

4. Bluetooth Receiver:

Possibly a bad Bluetooth receiver having intermittent problems. A faulty Bluetooth receiver with infrequent issues is another potential reason for a car radio with an aux that repeatedly switches between the AUX and radio modes. This issue could occur if the Bluetooth connection between the device—such as an iPod—and the vehicle’s audio system is weak or unreliable.

When this occurs, the head unit can believe the device has been removed and switch to the most recently listened-to FM frequency station.

5. Faulty Audio System:

Aux only car stereo? If the audio jack isn’t working correctly, the automobile radio may switch from car stereo with aux audio or mode. It can result from an audio system’s software or hardware problem, such as a damaged audio jack or an audio control panel. In these situations, the radio can suddenly return to radio mode.

6. Automatic Station Switching Feature:

A feature of some car audio systems or car radio with aux automatically searches for available stations and switches to the one with the strongest signal. It can detect and switch to other signals even if you’re on other channels or utilizing your Aux connection.

Therefore, if this option is turned on, the aux car stereo system may change channels and interfere with your transmission signals.

7. Incompatibility with the Audio Device:

Even though this issue is not very common, it may cause people switching problems. Your car radio may malfunction if you utilize unsupported gadgets with it.

People have occasionally mentioned running into this problem with their phones and iPods. Due to mismatched devices, you may also experience a similar aux-to-radio switching problem or .

Because of this, switching your AUX station to the radio is straightforward in your automobile. You can avoid that by not carrying too many electronics in front of your car.

7. Check the Docking Connector:

You might need to examine your docking port if you use Apple gadgets (such as the iPod or iPhone) in your automobile. Radio switching is unaffected by the absence of an illumination wire on the car radio but is affected by the presence of a docking connector.

Ensure the connector transmits audio when the gadget is connected to your automobile rather than just charging it. Your radio won’t be impacted if it’s in charging mode. Your connection will suffer if your docking connector is dirty or broken, though. As a result, you can continually switch from AUX to radio on your radio.

8. Replace Weak or Damaged Antenna:

Although the outcomes of this troubleshooting may seem ambiguous at first, they might be somewhat surprising. The antenna captures the entire signal from your car radio and transmits it to other devices, and vice versa.
