Car radio interference can be caused by a number of factors, including:
Electrical noise from the vehicle's engine or other electrical components
Electromagnetic interference (EMI) from other devices in the vehicle, such as cell phones or GPS units
Radio frequency interference (RFI) from external sources, such as power lines or radio towers

How to Fix Car Radio Interference

There are a number of things you can do to fix car radio interference:
Check the vehicle's electrical system. Make sure that the battery is in good condition and that the alternator is functioning properly. Loose or damaged electrical connections can also cause interference.
Move devices that may be causing EMI away from the radio. This includes cell phones, GPS units, and other electronic devices. If possible, use these devices in a different part of the vehicle.
Install an RFI filter. This device can be installed between the car radio and the antenna to block out unwanted signals. RFI filters are available at most auto parts stores.
Upgrade the car radio antenna. A better antenna can help to improve the signal strength and reduce interference.
Contact a professional. If you are unable to fix the interference on your own, you may need to contact a professional car audio installer. They can diagnose the problem and recommend the best solution.
