How can a car navigate without an HDMl phone?

The first type: connect the mobile phone screen and the car screen through the MHL line.

To achieve this connection, three conditions must be met: first, the mobile phone needs to support MHL function, which is currently available in most Android smartphones; Second, there must be an HDMI interface in the car. This requirement is strict, and you need to pay attention when you look back; Third, we need an MHL line. MHL(Mobile High-Definition Link) is a high-definition audio-visual standard interface for mobile terminals. The MHL function can transmit the video signal and audio signal of the mobile phone to the external display device at the same time without other complicated settings, which is quite simple and convenient.

The method is simple. Connecting the MHL cable to the USB port of the mobile phone and the HDMI port of the vehicle at the same time can automatically realize screen mapping, and then perform related operations. In addition to the MHL line, mobile phones can also project car screens, televisions and computers.

The second type: connect the mobile phone and the car screen through CarPlay system.

CarPlay system is an in-vehicle system independently developed by Apple, which is used to help the iPhone and the in-vehicle screen realize interconnection. At present, many vehicles in China are equipped with CarPlay system, which users can use to transfer their iPhone.

The device is connected to the car screen. Please note that only for iPhone, other Android phones are not supported.

The connection method is also very simple. Just plug the USB end of the Apple data cable into the car interface, and then plug the light interface into the mobile phone. At this time, your iPhone will remind you to turn on the siri voice assistant, and the vehicle will automatically start CarPlay. It is worth noting that the current CarPlay only allows the use of Apple's own navigation map, and does not support third parties. Both mobile phones and CarPlay support simultaneous input of search location and simultaneous entry of navigation interface.

The third way: the most commonly used way: the mobile phone screen displays the picture, and the vehicle plays the voice.

This is a common way and the most helpless way. That is, the mobile phone is connected to the vehicle-mounted system through the wireless Bluetooth function, and then the map route is displayed on the screen of the mobile phone, while the sound is played through the vehicle.

Here, I hope everyone can buy a mobile phone stand and fix the mobile phone in a suitable place, which is convenient for car owners to watch and prevent unnecessary dangers caused by improper mobile phone position and line of sight shift.
