It is mainly divided into three parts: about car selection, about car use, and sharing of recorder installation.

— [about car selection]–

Talking about your own driving situation, the place of work and home is 50 kilometers, that is, you have to run 100 kilometers every day and spend 3 hours in the car every day. You have to choose a car that is fun to drive and a good stereo.

1. SUV or car?
As the previous driving is Teana, has been driving for 8 years, has been accustomed to the car driving experience, and driving on urban roads, so did not consider the SUV.

2. Price range?
It is also because the onstage car is Teana, so the change does not consider this price range, to change for a better one, C-class, 3-series, A4L does not feel necessary, lock 40W-plus models. And this price range is also the common E grade, 5 series, A6L. For those over 40W, the 5-series E grade can only be the lowest.
A6L: the most cost-effective, but directly PASS, do not know why, also did not go to the test drive
Class E: went to the test drive, the interior is very luxurious, but I don’t know why it feels similar to Teana, just for the luxury identity, and maintenance seems to be more expensive, more than 400,000 to buy a 1.5T, a little awkward. PASS.
5 Series: also went to the test drive, the test drive is 530Li, compared with the E class, driving is really different, feeling is a tight rubber band, easy to handle. Due to the budget, only 525 is considered.

3. Standard axis or long axis?
During that time, I often mixed with the forum, and some riders often suggested that the 525 should consider the standard axis, because the long axis of 525 is not genuine leather, and it has low power, only 184 horsepower. Although the standard axis 525 has the same horsepower, it is also a leather seat, and the driving experience of the standard axis is better than that of the long axis.
All right, lock on 525i.

4. What color?
Mediterranean blue is very beautiful, but there is a Volkswagen with a similar color at home, so I don’t think about it. Carbon black is also good, but domestic ones also have this color, do not consider it. Cyan, a unique imported color, also looks special.

5. Need to be equipped with options?
As I spent almost 3 hours a day in the car and listened to music for a long time, Harman had to be installed.

Okay. Finally selected as 525i, stone cyan, with Haman. After asking about the price for many rounds, about 43W landed.

The point is that there is no car!

Either it has cyan, but not Haman, or it has Haman, but no cyan. Do you want to change it to 530ights and ask the price? it’s too expensive. Don’t think about it.

Due to the epidemic, there were few imported cars, and the 525i could not find a suitable one at that time. A family of four, sometimes going out to play, might as well buy a long-axle one.

525Li? Synthetic leather, low power, and such a long car, although it has not been test-driven. But it doesn’t feel right.

Gnash your teeth and put on 530Li. Full of power, large space, carbon black + volcanic red interior, looks passionate.

Take a look around, and finally choose 530Li, get down 47.4W, with Harman. For five years, the interest is a little high. Buy early, enjoy early, and endure slowly. At the end of April, I got my own Dream Car!

— [about using cars]–

1. Driving experience: a few days before I started driving, I felt a little longer than the sound of nature, and the feeling of driving a dragon boat was very inertia. Gradually become familiar with the length. Choose Sport mode, really feel full of power, gently step on the throttle, take-off feeling, too cool.
But often in traffic jams, it is useless to drive this mode. It is generally the default Comfort comfort mode.

2. Fuel consumption: due to the fast way to and from work, there are few traffic lights, the fuel consumption is generally between 6-7, or even as low as 5.5 (as shown in the following figure). It is much more fuel-efficient than the previous Teana. Filling up even shows that it can last a 1000KM.

3. Space: the back row is really big enough, but I don’t sit on it. Give your family a comfortable seat. The space in the trunk is too small.

4. Central control: the navigation of the original car is not used to use, but it is still used to using mobile phone Amap. Since I don’t have an iPhone, Baidu’s Carlife needs to be plugged in, and the resolution display is very low, so it has been useless for two days. Always use cell phone bracket to drive navigation.
For the reason of work, two mobile phones were needed, and the spare phone was later replaced by Apple. Carplay is really convenient, QQ Music and Amap, and it runs smoothly. Bought a second-hand iphone also with wireless flushing function, after getting on the car has been charging, has been connected to the Carplay.

5. Sound: Harman is actually very general, which may be better than that of the original factory. Downloaded some lossless music and put it on a flash drive to listen to. Especially the 5.1 channel songs, Harman’s effect is very good. In addition, found that the same QQ Music, Apple Carplay will be much better than Android sound quality?

6, maintenance: 100 kilometers per day, more than three months to the first maintenance, according to the manual, the first insurance only needs to change the oil, 4S is also recommended to clean the engine, spend several hundred yuan more. I didn’t want it. It cost more than 900 to change the oil and man-hours. It is now 1.4W km and is ready for a second maintenance.

7, tires: when the speed is about 70 per hour, step on several pits, because the air pressure is relatively low, keep it at about 2.3. There is no case of drum bags for the time being.

8, abnormal noise: the plastic of the center console, generally after the sun exposure, will BABALA sound, very crisp. Although it does not affect the use of cars, as a car at this price, this problem is very low-level. Is it difficult to solve? In addition, the co-pilot’s seat belt button, sometimes bumped into the B-pillar will be abnormal.

9. Modification: think about changing this and that before buying. I have been driving for half a year, but nothing has been changed. Only a recorder is installed.

— [about the recorder]–

The choice of recorder mainly considers three aspects: 1, security; 2, easy installation, not too much interior decoration; 3, high hardware configuration and clear video.

As for safety: because there is an airbag in the position of the 5-series A column, it is not considered to take the safety box or cigarette lighter, because in both cases, the recorder power cord will press the airbag. I think there are security risks.

About installation: For a new car, I don’t want to remove too much to avoid abnormal noises. Therefore, I chose the currently popular one: wire-free recorder. Draw electricity directly from the anti-glare plug.

Regarding recorder parameters: As far as I know, the current mainstream CPU programs include Huawei Hisilicon’s Hi3556 and Taiwan’s Lianyong’s 96675, which are the current mainstream flagships. However, the Huawei HiSilicon 3556 has a maximum of 1600P, while the Lianyong 96675 can reach 1944P. Therefore, we chose the couplet. The current mainstream of photosensitive chips is Sony’s imx335.

About the recorder type: Choose the hidden one for more beautiful appearance. External models are not considered.

Personal hands-on skills are okay. According to the video tutorial, it is not difficult to install it by yourself. Let me share it with you below, which may be helpful to you.
