When i changed my car battery the radio resett

Have you ever replaced your car battery and noticed that your radio settings were lost? This is a common occurrence and can be frustrating, especially if all of your presets were tuned perfectly for your favorite stations.

The reason for this is that car stereos often have a memory function that saves your preferred radio stations and settings. This memory function is powered by a small battery within the stereo unit, known as a memory or backup battery. When the main car battery is disconnected during a replacement, this memory battery loses power and your settings are lost.

However, it’s important to note that in some cases, there may be an anti-theft feature that requires a code to be entered before the stereo will work again. This code is unique to your car’s stereo and can often be found in the car’s manual or paperwork.
