Turn the car into multimedia WIFI base station

—iton similarities and differences Car cat C1 evaluating

First of all, I would like to thank Lei Feng.com and Similarities and Differences Auto Meow for providing the opportunity to try.

When we buy a car, in addition to paying attention to the power, fuel consumption, engine parameters, appearance and other hard parameters of the car, multimedia functions are also a factor that we often need to consider. However, for some low configuration cars or old cars with a long history of purchase, the multimedia function may not be powerful due to cost and technology at that time.  

With my Toyota Corolla two thousand and ten For the model, the central control multimedia player only has a single disc CD Play and FM FM 、 AM Function, simple single line LCD display, no Bluetooth, no USB Interface, let alone none SD Card slots and AUX Line input interface. If you want to listen to songs during the journey, you can either listen to the "songs inserted in advertisements" of FM radio station or play them CD Music on disc. CD Disc due to CD Format and CD disc six hundred and fifty The restriction of Mega maximum capacity eighteen It is very troublesome to change the CD frequently. If the third-party multi-functional multimedia central control assembly is replaced, at least three thousand The installation is complicated, and the circuit inside the vehicle needs to be modified, which may cause potential safety hazards. I had to make do with it until now, until Lei Feng won the lottery on trial C1 After a lot of research and use, my car can finally be comparable to the multimedia functions of high-end cars.

Chapter I Appearance

Receive different and similar cars C1 After the package of, I can't wait to open the outer package. What I see in front of me is a white box.  

On the side of the car, the model, color and network parameters of the car are written.  

Our car miao C1 It's a black move 4G edition. Mobile TD-LTE 4G Compared with garbage TD-SCDMA For example, the download speed has increased more than ten times. support 802.11B/G/N wifi Network standards, and support 5V 2A Of USB Charging output.  

After opening the box, the cat is placed in the middle, and the lower layer is AUX Connecting line and instructions.

Similarities and differences: Chemiao is ready to move for our trial players 4G The size and specification of the network access card are micro sim Card, iphone 4 and 4S Same style.

  The front of the car meow is very simple. The smooth mirror shell is printed with the car meow APP Download the QR code of. There is a blue one right below the QR code LED indicator light. When the power supply is connected, the blue indicator lights up, so that we can observe whether the car has been powered on and started.  

The back of the car is made of frosted material, and the brand, model, production company and company website are printed in turn.

    Considering that most of the cigarette lighters are near the gear and handbrake, the main body of the car and the cigarette lighter are connected by a movable rotating shaft, and there is about ninety The degree of rotation is convenient for us to adjust the posture of the car and prevent interference with our gear.  

There is one on the right side of the car Micro Sim Card slot, and one reset Key. When the car crashes or makes an error, long press reset Press the key to restore the factory settings.

There are two standards below the main body of the car USB Interface. It should be noted here that our batch of trial cars C1 Is moving 4G Version, the first of this version USB The interface has been defined as AUX out Interface, no charging function measured. the second USB Interface provision 5V Voltage 2A Maximum current charging output.

Chapter II: Installation.

Don't look at the car C1 The design is very large, but with a rotatable body, the actual installation is very easy, and will not interfere with our gear engagement and handbrake.

Take my Toyota Corolla as an example. When the car's meow is inserted into the cigarette lighter, whether it is in first gear or third gear, the hand gear will not touch the car's meow. Don't worry about blocking and interfering with our gear engagement.

  This is the third gear  

This is the first gear

AUX OUT Interface, which needs to be inserted with the machine USB turn 35mm Connector cable, 35mm The interface end is inserted into the AUX in Interface to realize the AUX Mode playback. I will explain this function in detail later, with a hidden skill.  

When the car lighter is powered C1 The blue indicator light stays on, indicating that the car has started working. Wait a minute, the car is meowing wifi The signal will be sent out. Via mobile phone wifi Interface Search Carmew-xxxx Signal, default password twelve million three hundred and forty-five thousand six hundred and seventy-eight , you can connect to the car's wifi Has.  

Chapter III Charging

Car cat C1 The second standard of USB Port support 5V Voltage, 2A Maximum current charging output. After actual test, Meilan note2 The maximum input current can reach 1.1A 。

Since I don't have a professional current, voltage and power detection instrument, I have to use the built-in debugging interface of the mobile phone to detect the real-time charging current (input it in the dialing interface *#*#3646633#*#* Then you can open the debugging interface hardwaretesting\power\chargebattlery In the interface, you can see the charging current. only MTK CPU This interface can only be opened for mobile phones.)

Up to when the screen is lit 1.1A , the charging current will be higher under the black screen. Compared with other on-board equipment, it is a stingy standard configuration 5V 1A In terms of charging interface C1 Go straight 2A "Quasi fast charging" interface, which is full of sincerity.

Enter the music interface, and the top bar displays the current FM The frequency of the transmission. Click to change.

Car cat C1 The humanized frequency setting is that when you change the frequency C1 It will automatically search the existing FM Frequency, and then avoid existing channels. Recommend an optimal frequency to avoid FM The frequency between them is too close to interfere with each other.

The default local music playlist is empty. click + The music folder menu will pop up after the number of, check √, and the music in this folder will be added to the local playlist. The same is true for deleting music. If you uncheck √, the music in this folder will be automatically removed from the list.

The control menu at the bottom can control single song, multi song cycle and random disordered play, the previous song, the next song and pause music. The push button can be selected through the car C1 Push the music out, or play it through the phone's built-in speaker.

If the mobile phone is not installed APP , or via DLNA Push to the car C1 . Common Android phones have been supported DLNA Pushed. Meizu MX2 For example, as long as it is connected to the car C1 Of wifi , enter the native music playing interface, you can see wifi Mark the fan-shaped DLNA Button, click and select CarMew-Music , you can push the music to the car C1 , very convenient.

Baidu Music and Kugou Music Player from a third party can be used in the recommendation tab. As long as they are downloaded and installed, the music can be played through DLNA Push to the car C1 On.

Chapter V Track Record

Car cat C1 built-in GPS Module, as long as it is powered on, turn on GPS Track recording function, GPS The module will automatically record the driving track in the background and stop ten It will be automatically uploaded to the server in minutes. In the future, after logging in with our mobile phone number on any device, we can download our own driving track, which is stored in the cloud for one year.

Each track is listed in preview list mode according to the timeline. Click any track to enter the track details page. The map is called Baidu map. In Baidu map, you can zoom in and out of the map, and the track record is very accurate. If you drive twice in one place, there will be two tracks.

I traveled hundreds of kilometers in southern Liaoning on business C1 It's all recorded for me, too IMBA Has.

Chapter VI Description and Areas for Improvement

There are several points to be explained:

one , Car cat C1 The official flow card is in the first quarter one hundred Meta contains 6G Traffic, monthly 2G , can only be used in the current month, and will not be transferred to the next month.

two . If the flow card is inserted in the mobile phone, you cannot make calls or send SMS messages. Even if ten thousand and eighty-six It is also not allowed to call or send text messages, so we want to ten thousand and eighty-six It is impossible to check the flow and balance.

three The official engineer said that the WeChat official account of Carmail would be opened in the future. After binding your Carmail device in the official account, you can query the traffic package, remaining traffic and service life.

four 、 GET A hidden skill, don't think aux only out Function of, aux The interface also has aux in Function of. Similarities and differences C1 Quite low-key, didn't write it out. That is, when 35mm Plugged into a car aux in Interface can be implemented aux out Function, which allows the music of mobile phone to be transmitted through aux The cable enters the vehicle.

When 35mm Plug in the mobile phone mp3 Wait until the car is installed APP On the device aux in Function, the mobile phone mp3 And other devices 35mm The wired cable of the interface is output to the car C1 , Launch FM Signal, realizing on-board FM FM Reception of.

five , based on the four Click to hide the skill AUX Cable 35mm The interface can be inserted into the mobile phone to realize the car borne hands-free answering of the mobile phone. If the mobile phone system supports the effect of music pause and fade in and fade out after a call, then the car will C1 It can completely replace the car borne Bluetooth hands-free audio, and the wired transmission is stable, using the mobile phone itself mic The quality of Tonghua is good, there is no interference problem, and there is no need to worry about the power supply of Bluetooth devices.

After two weeks of trial and research, I also found many areas that need improvement:

one 、 APP The connection terminal can only see the quantity, not the quantity mac Address and name. I hope to manage, kick out and speed limit the connected equipment in the future.

two 、 APP The client can only see the remaining value of the traffic, but cannot see the package and expiration date of the traffic card. I hope it can be increased in the future.

three . I hope you can communicate with China Mobile and transfer the remaining traffic to next month.

four , Insert SIM The card illustration is ambiguous and easy to insert reversely.

five The status bar of the mobile phone should be added with a pull-down resident function bar, with a shortcut icon for playback control, so that it is convenient to access APP In this case, pause and change songs directly and quickly.

six At present, there is no breakpoint memory function when playing music. Each time you open it APP , the concert will be played from the beginning, in the future ota It is expected to add music playing memory function after the update.

seven It is hoped that after the second generation of products, the storage capacitor will be added to avoid that when the engine is stopped and ignited, the instantaneous power failure of the cigarette lighter will lead to the power failure and restart of the machine.

eight , Android version of Goddard map and other navigation voice cannot be realized wifi Push. But if you use AUX This problem does not exist if the cable is connected.

nine The main interface signal is only displayed three 、 4G The network does not display the signal strength in real time. If the signal strength can be displayed in real time, you can know the current 4G The network status is up.

Chapter VII Summary

Through this period of experience, it is different from the car cat C1 With excellent appearance design, powerful functions and rich interfaces, music can be pushed to the car in wireless or wired mode FM FM, can be performed 2A The "quasi fast charging" mode with maximum current can also record the running track of the vehicle in real time, especially after lending the vehicle to a friend, so that it is convenient to understand the running track of the vehicle. In the long journey, we can not only access the Internet in real time and at high speed, cooperate with third-party players, but also listen to the best, latest and most popular music online, so that we will not be tired during the journey.

Car cat C1 , which is worth owning.

Thanks to the official engineer of the group @Su @ Joe Aaron , actively answer and solve our questions and submitted bug , my magic blue note2 Of APP Always flash back, unable to try, the engineer asked me to upload log After the log file is created, a total of five individual debug Version of APP , although there are still some flashbacks BUG , but this attitude of being responsible for users is very positive.
