Foton five-star three-wheel trucks are usually not equipped with music systems. Since they are primarily used as vehicles for transporting cargo, they are not as focused on providing entertainment and comfort features as passenger cars. Therefore, Foton five-star three-wheel trucks usually do not have a music system inside. However, some vehicles may be customized to suit customer needs and may include music equipment. The specific situation may vary depending on the model and configuration. It is recommended that you consult the relevant sales or service personnel to obtain accurate information.
