When buying a car at the beginning, the ease of operation of the multi-function square disk was taken into consideration. Listening to music, answering a phone or navigating on the road only requires a touch of the thumb. However, when choosing this transportation tool, I regret to cancel these choices for various reasons. With the development of science and technology, the Yilian Square Controller obtained from Lei Feng's trial website has met the operating needs of his driving, and has really solved some bad habits in driving, making the journey safer.

I Unpacking

The lift off white package is adopted. On the top of the package box is a sticker for Lei Feng's trial use. In the middle is a picture. Below is the function promotion of Yilian Fangkong: intelligent safe driving assistant.

At the bottom of the box are some technical parameters of Yilian Fangkong, including the battery type, connection mode and the version requirements of mobile phones. This Yilian Square Controller supports both Android and Apple versions. It is applicable to current popular mobile phones and can be installed by scanning the QR code at the bottom of the box.

There is not too much decoration, including the main body of Yilian Square Control, the user manual and a button battery. When we opened this box in front of everyone, we were surprised. Most people didn't know its purpose. Now the development of technology products is changing with each passing day, which is understandable. As a car owner, especially the steering wheel is not multifunctional, it is recommended to add this Yilian Square Controller to make your driving safer.

II Details

The front is designed with petal shaped keys. Raised arrows are designed in all four directions. It has obvious tactile recognition function in operation. It can be operated blindly during driving. It can be easily realized for answering the phone, navigation, etc., to eliminate potential safety hazards.

The connection between the Elion Square Control and the steering wheel is also very simple. The lateral texture is designed on the inner side of the square control tape, which increases the friction with the steering wheel. It is very firm after installation.

In the operation interface, when the battery is installed, an indicator will be displayed. This indicator will only flash once after the battery is correctly installed, and will not be prompted in subsequent operations.

The flip buckle is made of aluminum alloy, which can not only ensure its strength and prolong its service life, but also reduce its weight.

This Yilian Square Control adopts the Bluetooth 4.0 connection mode. The required power supply is a 3V button battery, model CR2032, which can normally be used for more than 6 months and is easy to purchase in the market.

The battery compartment is marked with the positive pole facing down. The design of the battery compartment is also very special. On the one hand, it can place the battery, and on the other hand, it can lock the buckle when the buckle is overturned in place, playing the role of double insurance.

III Usage

The manufacturer provides four color versions, namely Moonlight Silver, Champagne Gold, Vitality Blue and Elegant Grey. This time, the author got a version of Vitality Blue. Because this Yilian Square Controller is small in size, the choice of multiple colors does not play a major role in embellishment, but it can provide some users with more choices.

The manufacturer provided an installation video on the official website, but in actual operation, when turning the steering wheel to the 180 ° position, it is more convenient to install this product.

Installation renderings.

The mobile phone scans the QR code in the manual and registers according to the prompts. In addition to using mobile phone number to register, you can also use QQ, WeChat and other social accounts to log in, turn on mobile Bluetooth, and then match with Yilian Fangkong.

The display interface of the mobile phone is consistent with the operation interface of Yilian Fangkong, which is divided into four areas. The upper left corner (red) is the navigation page, the upper right corner (yellow) is the music page, the lower left corner (blue) is the shortcut navigation, and the lower right corner (green) is the phone page. Long press these function keys to directly switch to their corresponding function areas. The round button in the middle is a voice function key, which can be used for voice operation after long press. This voice assistant of Yilian Square Control, in cooperation with the famous iFLYTEK company in China, has a voice library customized for driving, making voice operation more accurate.

The use of this Yilian Fangkong is not only to control the mobile phone, but also to project the content displayed on the mobile phone screen to the vehicle mounted display screen, making the visual effect better. Upgrade the memory card of the original vehicle navigator to make the connection more convenient. These contents can be found on the official website, and can be easily switched according to your own model and navigation.

This is the end of the evaluation for the time being. The next evaluation will be the use of projection to the large screen.
