What is the reason why the USB device of Mercedes-Benz C200 cannot be read?
2 Answers
Mercedes-Benz C200 USB device cannot be read because the power of the car USB interface and the mobile phone interface is insufficient. USB car charger: Usually referred to as USB car charger for short. It takes advantage of the universality of USB, which is widely used in various charging interfaces. Combined with its application in cars, it converts the 12V-DC and 24V-DC in the car into the common DC-5V voltage for USB and other charging devices. Common specifications of USB car chargers: Output: 5V-DC-500mA; 5V-DC-700mA; 5V-DC-1000mA; 5V-DC-2000mA.
I've been driving a Mercedes-Benz C200 for two years and have encountered the issue of USB devices not being recognized several times, each with different causes. The first time, the USB drive didn't respond at all. After a lot of troubleshooting, I realized the issue was the drive's format: the C200 only recognizes FAT32, and my USB was NTFS. I had to reformat it on my computer to make it work. The second time, the port was clogged with dust, and a gentle cleaning with a cotton swab restored functionality. Another possible cause is insufficient power supply. The car's USB ports have limited power output, so older, high-capacity USB drives or incompatible cables might not work. Testing with a smaller device can help identify the issue. Software updates are also crucial. If the car's system hasn't been updated for a long time, bugs can occur. I recommend regularly visiting the dealership for updates or checking the menu for new versions. If none of these solutions work, the port might be internally damaged or have a circuit issue, and timely repairs can prevent further complications. Although it's a minor issue, it affects music and navigation, so I believe addressing it early reduces hassle and ensures driving enjoyment isn't compromised.
