The radio in your car is a vital component that makes your drive more enjoyable. When traveling to and from work, it is a best buddy and makes weekend activities more pleasant.
In this post, we’ll guide you through diagnosing and fixing the problem of an unpredictable channel change on your vehicle radio. Additionally, as this issue is known to affect the Chevy and Mazda 6 vehicle models more commonly than others, we will concentrate on them specifically.
Car Radio Keep Changing Stations by Itself? 5 Main Reasons
1. Radio Troubles:
The sensitive or malfunctioning buttons on your car’s frequent radio station switching may be due to accidental control pressing. If the radio controller on the steering wheel is very sensitive, it may introduce undetected taps.
Give the radio control buttons on the steering wheel a moment’s thought before you start trying to solve problems with it. This easy step ensures that you eliminate accidental presses as the possible cause.
2. Faulty Control Buttons:
Sometimes, control button glitches rather than human actions are the primary cause of accidental changes stations on its own.
Using heated air to clean the buttons is one way to tackle issues related to dust. If it doesn’t work, you should do a deeper cleaning that involves removing and cleaning the controls.
If the issue still exists because the switch isn’t working correctly, replacement is your only option. Some car models may experience swift wear and tear of the steering wheel buttons, resulting in widespread faults. Finding this usually entails seeing many buttons on the steering wheel malfunction.
3. Electromagnetic Interference
Electromagnetic interference may be the root cause of your vehicle’s radio’s sudden station shifts. When the power supply of the stereo system is not enough grounded or encounters excessive resistance in its wiring system, interference occurs.
A malfunctioning alternator is a frequent cause of this interference and can lead to electrical issues that impact your car’s speakers and radio, among other electronic components.
Notably, problems with the alternator or battery may affect vehicle radios and lead to more general electrical system faults.
4. Radio Controller Wiring Fault:
Your car stereo’s wiring may malfunction if you constantly switch stations. Your sound system issues can originate from an accident or water damage you recently experienced. Such events might result in electrical damage, which would explain the problems that have been noticed.
Identifying the location of the issue is critical in this case. If the incorrect cable connections are fixed, the problem should be resolved. But if the wire is damaged, you’ll need to replace the damaged pieces to get your vehicle’s audio working again.
5. Old Car Stereo:
If none of the above-suggested fixes solve your trouble adjusting the radio station, it may be time to look at your vehicle’s radio’s circuit boards. This is especially important if you are listening to music on an antique stereo from the past.
These motherboards are likely to to damaged because of their fragile nature, mainly when there are power fluctuations. If all else fails and your radio seems ancient, it may tell you it’s time for an update.
Due to years of usage, wear and tear, and possible heating problems, repairing these complex motherboards may be difficult and expensive.

4 Easy Ways to Resolve Car Radio Automatic Station Changes:
1. Examine Vehicle Grounding:
- To evaluate the vehicle’s grounding, use a multimeter used to measure voltage.
- Before the exam, ensure all power sources are off to ensure safety.
2. Check For Open Wires:
- Examine and fix any exposed or loose wires that connect the stereo to the antenna.
- Examine and replace any broken wires that link the stereo to the speakers and power supply.
- Check for tight speaker connections to ensure the integrity of the entire system.
3. Handle Humidity Concerns:
- Recognize how humidity affects radio reception.
- Look for leaks in the sunroof that might bring in moisture and produce static or inadvertent station changes.
- Reduce by momentarily turning off power windows and signaling to let moisture escape.
4. Firmware Update:
- Save the firmware update to your computer after downloading it.
- Transfer the unzipped folder to your USB drive (the one included with your radio), ensuring there is enough room on it.
- Place the USB drive into the port on the radio.
- Turn on the receiver, hit MENU to start the boot-up menu, and then choose “Firmware Update” to start the installation procedure.
Finally, the purpose of these suggestions is to assist in locating and resolving the problem of your car’s radio. If issues continue once the audio is fixed, look into manufacturer firmware upgrades or seek expert help for a complete fix.
