Below are the specific reasons why the USB port in a Cadillac cannot charge: 1. Blown fuse: The fuse for the vehicle's USB port may have blown. Refer to the vehicle's user manual to locate the corresponding fuse. If it is found to be blown, replace it with a spare fuse promptly. Damaged data cable; loose charging port springs on the phone, leading to poor contact. 2. Insufficient current output: Check the application range of the USB port in the vehicle's user manual. Generally, USB ports used only for data reading provide a current of 0.5A, whereas a phone charging port requires at least 1A current output.

How to Take the Subject 2 Driving Test on a Rainy Day?

Here are some tips for taking the Subject 2 driving test on a rainy day: 1. Check the mirrors: Before getting into the car, thoroughly clean both side mirrors. On rainy days, the mirrors are likely to be affected by fog or water droplets, which can obstruct your view and make it difficult to observe traffic behind you or accurately judge reference points. 2. Don’t close all windows: Avoid sealing all windows tightly due to the rain. If all windows are closed, the lack of air circulation inside the car can cause the windows to fog up, significantly impairing your visibility and potentially creating unsafe conditions.

What is the difference between a car amplifier and a DSP?

The differences between a car amplifier and a DSP are: 1. Connectivity with a computer: An amplifier cannot connect to a computer; a DSP can better manage the amplifier through a computer. 2. Effects: An amplifier does not have the processing capabilities of a DSP, resulting in poorer sound quality; a DSP can actively divide frequencies, apply delay processing, EQ tuning, etc., to make the audio sound better. A car amplifier is the audio power amplifier in a car audio-visual system. Its function is to select and preprocess the input audio signal, amplify the power, and enable the electrical signal to drive the speakers.
