- Upgraded Chip: This CD player is designed for vehicles without a built-in CD player. It features an advanced chip with a built-in audio decoder and FM transmitter for improved reading, noise reduction, and efficient data transfer. Powered via USB/TYPE-C cable, it eliminates the need for extra adapters and minimizes power consumption. - Versatile Playback: With three playback options supported, this CD player ensures a method to suit your needs. It is compatible with WMA and WAV formats, allowing you to enjoy your favorite music CDs through your car's factory radio and sound system. - Broad Compatibility: This CD player works with thousands of car models and is suitable for factory stereos and aftermarket radios (both Android and non-Android) that have USB/TYPE-C or AUX ports. It also works with desktops, laptops, smart televisions, active speakers, and amplifiers. - AUX Compatibility: If your car features a 3.5mm AUX port, this external CD player is compatible and includes a built-in audio decoder. For vehicles that do not support WAV audio files, simply connect via AUX input for audio playback. (Connect the CD player's USB port to the car’s USB port, and the AUX port to the car's AUX port.) - Compact and User-Friendly: Plug the USB/TYPE-C interface directly to use—no external power supply needed (for Android 4.4 and above). Its small size allows easy storage in the glove box or alternative locations. (Note: Allow 10-20 seconds for initial reading.) - Ultimate Solution for All Cars: In instances where the USB/TYPE-C connection or AUX transmission fails to play CDs, the built-in FM transmitter allows you to play CD tracks via your car radio on the same FM frequency.
