To change songs to new ones on your 2017 BMW X3, you can follow these steps: First, download the new songs you want to a USB flash drive or other compatible storage device. Then, connect the storage device to the vehicle's USB interface or other audio input interface. Next, through the vehicle's audio system control interface, find the audio input option in the menu and select the interface to which you connect the storage device. In the audio input options, you should be able to find a list of new songs on your storage device. Just browse the list and select the new song you want to play.

This method of replacing new songs on the vehicle is mainly because modern cars are generally equipped with multimedia audio systems that support playing music through external devices. By connecting the storage device to the vehicle's interface, the audio system can read the music files in the storage device and play them back. This design allows car owners to update and change car music at any time according to their own preferences and needs.

In addition, many modern cars also support Bluetooth audio technology, allowing car owners to connect their mobile phones or other Bluetooth devices via Bluetooth to play music wirelessly in the vehicle. This wireless connection method also provides car owners with a more convenient choice.

In general, by replacing new songs on the vehicle, car owners can enjoy a personalized music experience and update their favorite music content at any time. This not only enhances driving pleasure but also makes long journeys more enjoyable.
