Reasons for unsuccessful external CarPlay connection: Damaged phone data cable: Check if the phone data cable has any damage or breakage, and whether there is any foreign matter attached to the metal contact terminals on the USB plug and phone plug or if the surface is oxidized. Internal damage to the USB female port of the external USB HUB of the car stereo: Inspect the USB female port of the external USB HUB of the car stereo for any internal damage and whether the contact metal pieces can maintain good contact with the USB male plug. Check for loose connections between the car stereo and the external USB HUB: Examine the connections between the car stereo and the external USB HUB for any looseness. To avoid poor internal contact caused by prolonged oxidation, you can repeatedly unplug and replug the two connectors of the cable.

What are the causes of transmission failure in the Mitsubishi Outlander?

The causes of transmission failure in the Mitsubishi Outlander are faults in the transmission computer or electronic components, or impurities or severe shortage of transmission fluid. Below is an introduction to transmission-related content: 6AT transmission: Except when shifting from P to D at the start, or from D to P when parking, the D gear can be used from start to finish. The Sport gear can be used when starting, but on flat roads, the speed increase with Sport gear is not as fast as with D gear. The S gear has excellent acceleration performance and is used for overtaking after reaching a certain speed. When the car is running, shifting the D gear to the left switches to M gear mode, and the gear can be controlled by pushing the gear lever forward or backward. Classification: Car transmissions can be divided into manual transmissions and automatic transmissions, with AT being the commonly referred to automatic transmission. Generally, automatic transmissions have gears such as P, R, N, D, 1, or L. 6AT indicates six forward gears, meaning there are six sets of gear groups with different transmission ratios. Others include 4AT, 8AT, 9AT, and even 10AT. Although the preceding numbers differ, they are all derivatives of automatic transmission technology.

Where is the AUX interface of Mercedes-Benz S350 located?

The AUX interface of Mercedes-Benz S350 is located on the right side inside the glove box, which is a flat square socket with multiple small pins. AUX is an audio input interface. The basic working principle of the AUX interface is that after connecting the AUX interface, the audio in electronic products can be connected to the car audio through the headphone jack and AUX interface, and the audio can be played on the car audio broadcast facilities. The USB interface can be used to insert a USB flash drive to play audio. When using it, insert one end of the connection into the AUX interface and the other end into video players such as mobile phones, MP3, MP4, etc. In this way, you can listen to songs or niche music anytime and anywhere, not limited to car music CDs. However, if the playback device runs out of power, the music will also stop (the interface is generally a 3.5mm labeled headphone jack). Aux is the abbreviation of Auxiliary, which is an additional signal line design. In general audio equipment, in addition to the official output and input terminals, there are often several input and output terminals labeled Aux as spare connection terminals. When there are special applications, such as additional sound output or input, this type of terminal can be used. This type of spare terminal or line, regardless of input or output, is collectively referred to as Aux. Function: The AUX port is an asynchronous port, mainly used for remote configuration, dial-up connection, and can also be connected to MODEM through a transceiver. It supports hardware flow control. The AUX port and CONSOLE port are usually placed together because their respective applicable configuration environments are different. The AUX interface establishes a command-line connection between the user and the device, performing some operations that are usually impossible in user mode, such as initialization, restoring initial configuration, correcting abnormal user mode, etc. It provides a fixed port for the device, which can be used as a common asynchronous serial port with a maximum speed of 115200bit/s. With the AUX interface, remote configuration, line backup, and other functions of hardware products can be achieved. Note: When using the AUX interface, pay attention to buying the correct connecting cable and ensure not to plug the audio cable into the wrong port. It is best to follow the steps in the product's user manual when using the AUX interface. If you still don't understand, you can consult the product's official website or call for advice.
