What is the difference between an in-car SD card and USB?
1 Answers
The difference is that USB can be used directly in the USB port, while an SD card needs to be inserted into a card reader to function. Below is some information about USB interfaces: 1. Functions of a USB interface: Insert a USB drive to listen to music, charge a phone, use a USB car cigarette lighter, car vacuum cleaner, radar detector, or dashcam. 2. Precautions when using a USB interface: Connecting a phone's USB to the car's USB input port is ineffective—it won't be recognized as a USB drive, nor can the car play music from the phone. The car stereo must have the phone's USB driver installed. If the car stereo has an AUX interface, you can use an audio cable—one end connected to the phone's headphone jack and the other to the stereo's AUX port—to use the stereo as an external speaker for music playback.
