What does BND mean in cars?

[RileyLee]

BND in cars refers to the radio band switch button. Pressing this button allows you to select between 3 FM or 2 AM band radio stations. Below is a detailed introduction to the car radio: 1. Player buttons: The buttons on the car music player, such as PWR, MUT, AMS, LOU, and SEL/AF, are indicators for the car audio system. PWR: Press this button to turn on the device (any button on the panel can turn it on). Hold this button for more than 1 second to turn it off. MUT: Press this button to mute the playback. AMS: In radio mode, hold this button for more than 2 seconds to automatically save the received station to preset stations 1-6. A short press cycles through preset stations [1-6], each staying for 5 seconds. In MP3 mode, pressing this button selects the MP3 menu. LOU: Enhances low-frequency loudness. SEL/AF: Selects AM or FM bands. 2. Usage precautions: The player's input voltage is generally +12V. Excessive voltage can damage the player, while insufficient voltage will prevent it from functioning properly. Normally, insert the USB flash drive into the player first, then plug the player into the car's cigarette lighter socket.
