Why can't GAC Trumpchi play USB music?
2 Answers
GAC Trumpchi's inability to play USB music is caused by a damaged USB drive. Bluetooth can eliminate noise and echo: Equipped with advanced digital signal processors and voice devices, it is suitable for any harsh environment, eliminating background noise and echo, allowing both parties to enjoy high-quality call effects with an effective range of 10 meters. Bluetooth can automatically identify mobile phones: It can connect to mobile phones without the need for cables or phone holders. You can control the phone without touching it, even keeping both hands on the steering wheel, using voice commands to answer or make calls. Users can conduct calls through the car's audio system.
As an experienced auto mechanic, I've seen many similar cases. The main reasons why GAC Trumpchi's USB can't play music usually lie in the USB drive or system settings. The USB drive must be formatted in FAT32 - if you're using exFAT or NTFS format, the head unit simply won't read it. File formats matter too, with MP3 or WMA being commonly supported types. FLAC sometimes works, but APE or high-bitrate files may not be compatible. Also, don't overlook potential USB port issues - the interface might be dirty or have poor contact. Try cleaning it with cotton swabs first. Check the audio source settings in system options too - sometimes accidentally selecting Bluetooth or AUX causes errors. Try rebooting the infotainment system by turning off the power for a few minutes before restarting - many minor glitches get fixed this way. Outdated head unit software can also be problematic, so consider updating the firmware through the mobile app or at a 4S shop. Remember, don't jump to suspecting major faults first - starting with small checks can save you a lot of trouble.
