As more and more people start to equip their car with DVD player navigation, in order to keep up with the trend, you may heartbeat by this. So, you decide to buy a fashionable car DVD player and you go to the shop and see various kind of DVD navigation and be confused. The reason why you confused about may be that you are not understand the product at all. Therefore, before you go to the shop, it’s very necessary for you to do some little homework. You can refer to the following internal parameters for car DVD player navigation system for Audi A5(2008-2013) . More information about the device you can visit: .

First, the internal accessories of all-in-one DVD navigation as follows:

1. Movement, mainboard, baseboard.

2. The navigation module.

3. The Bluetooth module.

4. LCD and touch panel.

5. Radio frequency.

The heart part of the mainframe are: movement, mainboard and baseplate

Second, The basic principle of all-in-one DVD navigation.

There are two parts when talk about from the lr laser read data,Video and audio processing (image) processing of two parts

1. Audio processing.

General mimic panel audio processing characteristics: front audio output voltage is generally between 1.5 V – 1.8 V, this type of audio output voltage is not meet the requirements of the power amplifier audio input, general power amplifier is above 2 V, the level in Europe is in more than 3 V. So host mimic panel can not added power amplifier, if added will generate the cause of the noise. Listening with the original car’s speakers, the sound quality can’t compare with the original car CD players, not to mention the stand or fall of quality.

2. Video processing part

The key of Video processing is the definition. At present, a lot of manufacturers claim their products are digital screen, the screen resolution is 800 x480 = 800 pixels, analog screen resolution 400 x234 = 93600 pixels. This can only mean this product adopts the digital screen or mimic panel, does not represent the real resolution of the host, or pixels (clarity). And this process is completed through the host board and baseboard of the video signal.

(1). LCD digital screen’s technical parameters.

a. The distinction between high color and true color screen is that the price is not the same, the price of true color is higher than the high price of color screen.

b. The brightness of the display parameters is generally from 250-500, the brightness is above 450 can be classified as car Car gauge panel. That is to say, it can be used in the car, and under the bright light can clearly see the image.

c. The touch-pad’s basic distinguish. Reflection and non-glare (reflective is can prevent glare)

d. All digital screen resolution is 800 x 480 – this limit can never be reached, only infinite close to, the key is to see the video signal transmission circuit, digital circuit.

(2). Digital circuit design and transmission.

Digital signal of the vehicle display is use: red, green, blue three kinds for color transfer, there are eight primary colors of each color, can also be interpreted from the host read laser disc, at the end of the input to the LCD screen to ensure that the signal is 3 b* 8 = 24 primary colors. This is the digital circuit, the transmission way of all kinds of digital signal can’t be lost. Digital screen using a digital circuit is of 24 primary digital circuit design, and then transferred to the screen of the signal.

3. Radio turner. At present market, there are more and more manufacturer of radio high frequency head reflected that the radio signal is not good, has the current sound and noise, the main radio tuner anti-jamming ability is weak, it mainly because of the radio frequency head price.

Now as the price of the original car or shape is differ, in low-grade cars, when use after may install cameras, camera will not work or a flashing phenomenon, the main reason is that the original car of lamp power supply is not enough, did not reach the host need 12 v voltage. And some cars taillight voltage is only 8 ~ 10 v (mainly ashkenazi car), cause the host could not be started normally. The above video is about the car DVD player navigation for Audi A5(2008-2013) , take a look, it will provide you a better visual experience.

At present, there are more and more car DVD player navigation products on the market, which may make you feel confused when you need to purchase a new one for your loving car. You may desperately need to know the purchase tips for your car. Generally, the purchase tips is no big difference for different. The following passage is talk about the purchasing tips for car DVD player navigation. That may help you when you need to buy one for yourself.

1.Estimate its basic configuration (hardware is of good quality is guaranteed). First for DVD navigation, it is need to meet the basic functions of the DVD. It depends on the movement skinhead, which involves music, sound, audio quality and the sound quality deeply affect DVD. A good DVD uses a dual optical drive , that is, DVD, CD optical drives. Be sure to ask before you buy it, you need to compare multiple DVD players, choose the best one. Generally the price is relatively high the sound quality is higher, the owner can choose a best value for money.

2. The second is the images and Machine proportioning. There are two kind of DVD navigation screen, one is the simulation screen, now a relatively rare, another one is a digital high-definition screen. Now DVD navigation are generally 800 * 480 pixels, and generally there are two cases, (1). an analog electronic circuit + digital screen,(2). digital screen + digital circuits. The first case is that there is aberation and can not reach 24 true color, usually 16-18 bit true color, while the second is almost close to 24, that is, when we look at the screen it will be more clear. When buy DVD navigation the best choice is to select a dual-core model, which is dual-core CPU with two separate processing system. And the two CPU can not interfere with each other at work, which can ensure the accuracy and efficiency of navigation. Before we buy the car DVD player navigation, we need to have a basic understanding of the DVD navigation device’s function, if you encounter some products do not have the basic functions in a timely manner to navigate and do not buy this product, because mostly they are fake products, whichcan not be prolonged used, but also particularly vulnerable to damage. Users frequently need to repair, thus wasting a lot of energy and money.

3. Depends on it’s basic functions (whether all the functions can meet your needs). You need to figure out the DVD navigation’s basic functions, such as DVD player / radio / SD card / USB / Bluetooth / Rear view camera / GPS / AV input / party control settings.

4. Peculiarity: Only with peculiarity, can the device embody the owner’s taste. Compare with similar products to find out what the difference is. When compared with other brands if there are some other differences. For example, whether the movie Playback can play 1080P HD decoding, whether it support for 5.1 channel audio conversion, whether it possible to listen to music when playing APE lossless music, and whether it can swim 3G networks. Whether the navigation can supported 3D photo navigation, the background color of said light is stepless adjustment, radio acceptance is not there we will be able to understand the Chinese see the radio function is not to have a sound e-book reader, when precise GPS automatically granted, is not supported by large-capacity mobile hard disk information, we are now most people are used in smart 3G phone, the battery is not enough, is it possible to charge the phone, and so on, if there is a navigation are available, and that it is very suitable for our needs.

It’s not hard to buy a car DVD player navigation, the hard point it’s to choose the best one for you. View the following video, you may find the unique of the car DVD navigation.

GPS systems have a broad-spectruns. A GPS tracking system tracks packages or shipments. Shipping companies use tracking GPS systems. Personal GPS systems help those lost drivers to find their destination. GPS systems will also direct the driver around traffic jams and save a lot time during the commute time. There are no tools involved to install a GPS in a car. Installation only takes a few minutes. A GPS is a useful investment for those who travel frequently. To install a new car DVD player for your own car is not a big deal, but many people may think about the question how to update the navigation software? As the technology is of rapid development, so constantly update the naviagtion syetem software for your car DVD player GPS navigation is very necessary. So, how excactly to update the car naviagtion system software? Here, i’ll take Audi A4 2013 as an explame to explain the update method for the navigation software.

Update precudure:

Step one:

1.Find a suitable navigation software.

How to know whether a navigation software the proper one?

Screen resolution fitness. (This is important)

Resolution matching is the most important, such as your navigator resolution is 480 * 234, 480 * 272 may not be used or 800 × 480 version of the navigation software. If the resolution does not match the navigation software, will appear scrat, overflow screen, not full screen, black screen, button dislocation, even can not start, start the error or the phenomenon of death.

How to know oneself navigator resolution? Three kinds of methods, very simple:

<1> read the instructions. All products will be stated in the specification of general description.

<2> to manufacturers or dealers to ask.

<3> use of software testing. Resinfo and Navi examine are   test software is good, the two software download and introduced, at the end of the paper will focus on the paper.

2, system version matching. (this is not very important, most software is compatible with the full version)

Step two:

Download and install

Download channel, believe me, no need to say more, but search the Internet bubble forum, etc.. Source or a lot, a first step towards understanding the content, it is not difficult to find a suitable navigation software. We usually look for other software but is this a few methods. But the navigation software is quite special, special is the place where the file size is too large. The general software, a few megabytes, tens of megabytes to almost the same, The navigation system mostly is about 1.5G, the maximum has reached about 5G. This and the amount of data is directly related to, but with the continuous increase in map information points, believe that the volume of software will be huge. This software is not on a web site space, but is uploaded to the Internet professional SkyDrive space available for download.

Step three:

Decompress all understand, is the decompression software, combined perhaps some people confused. A navigation software is divided into two parts of the main program and map data (map data is also called “mapping”, some netizens nicknamed “rabbit”), many downloads will be the main program and map data are published as two links. This is because, with a navigation software with the use of map data, the main program for different versions of the same version and, vice versa, such as the earth, 800 x 480, 480 x 272, 480 x 234, 320 x 240 these resolution navigator to correspond to four Rucker main program, and map data you can use the same, so publishers, only released a map data, four main program on the line. Reuse that can make the resources, saving the upload time, and everyone to download the same map data, according to the P2P principle, also improve the download speed, for the benefit of both uploads and downloads.

Step four:

Set port speed. (very important)

1, the test port and speed: generally a navigator of the port and speed are fixed value, installed in the navigator on the navigation software is required by this value is to ensure that the received satellite signal. Port and speed by NAVI examine to test out, of course, there are some other test software is available.

2, set the port and rate: method of navigation software port and speed settings are different because of the different software. Some of them are very simple: for example, Kelid is to modify the NAVICONFIG.txt class file, modify the comm_config.txt file. Some are very complex: for example, the German high need to use sixteen hex editor to modify the Plugin.dll file, Papago need to use sixteen hex editor to modify the PaPaGO.exe file. Some are not set: for example, Route 66 port and speed are adaptive, without their own settings, navigation software will automatically find

Step five: Setting the navigation path.

The path navigation path is the navigator operation navigation software, essentially making navigator know which executable program is run the main program navigation software, the main program file suffix usually is.Exe. Navigation path set is divided into three types:

1.A navigator only installed a navigation software. The most simple, general navigator settings have navigation path settings, the path to the executable file.

2.A navigator with multiple navigation software. The first installation of multiple software, and then the navigation path navigation to the multi software executable file, at last set multiple software to the navigation software executable file. So open the navigator will first open multiple software, through multiple software can choose a specific navigation software to open.

Step six: Test and use.

The above steps are done, if true, you can use. The normal running of the program, the star, not normal, do not jump star drift, accurate positioning is normal.

The following vedio is about the car DVD player naviagtion for Audi A4, view it and you will get to know the device clearly. More information you can also visit:

According to many years’ working experience, car DVD player navigation is the simplest IPC, and can also regard as a big PDA with simple functions.

1. Most all-in-one car DVD player use WINCE ARM system

2. The internal parts of this product are: mainboard, CPU, RAM, ROM, display chips and audio chips.

3. The better product of this type is the Auto PC, and provides hard drive, which replaced RAM/ROM, while the rest is the same.

4. The software that developed on the operation system. Almost all the all-in-one car DVD player in the market offer variety of language options, but it lack of technical content, and the export price of the foreign countries is very cheap.

Different all-in-one car DVD player navigation system equipped with different operation system, such as win97, win 2000 and win xp. So, how to distinguish the quality and cost performance of such device?

1. Whether it use multi-core processor. The best way is see whether other program can be operated while open the navigation. The disadvantage of the early single-core processor is that when you use the navigation, you can not listen to the radio, or play DVD and CD.

2. The Bluetooth protocol version number and whether it support A2DP or not.

The outdated Bluetooth protocol can make the signal lost and speaking unsmooth when the cell phone connected with the navigation. While the bets advantage of the A2DP is that it can play all the audio which support Bluetooth through the car DVD player. No practical use, but feels good.

3. Whether adapt the digital panel. There is no big difference with the touch screen, the key point is the display chips.

4. Whether it has external port, such as USB port, AUX port.

5.  How many loudspeakers can it support? It’s a pity that the lower-middle all-in-one device can only support 4 loudspeakers. If the loudspeaker is more than 4 and you do not want to lose the media effect, then you have to buy another power amplifier to connect the GPS navigation or spend a huge money to buy a better all-in-one device.

6. Support malfunction steering wheel control. Along with the development of car technology, more and more lower-middle cars can support steering wheel control.

7. GPS chips. The kind of chips directly determines the quality and the speed of the satellite search, and it is an important index.

8. Extended function and software port, such as tire pressure monitoring and whole vehicle fault information gathering.

Pleasing to the eye and the convenience. The important embodiment of the pleasing to the eye is that whether the panel was added or fully fashioned, and

9. whether the color of the background light is in the same style with the original car.

Now, after my sharing, you must think there is no longer   mysterious with car navigation. And you must want to know more about the products, click here , you will find many wonderful products here just like the one in the following video.

Many car owners think that the built-in car navigation and AV products can perfectly match while driving. And nowadays, the car audio navigation has become the basic options for their car. But with the widely application of this device, the problems of the car DVD player navigation and audio-visual products has increased. This make many consumers got a question here: Are those car navigation and audio-visual products can guarantee their safe while driving?

1. Hidden danger one: The battery overheating.

Recently, the global line of Garmin GPS navigation manufacture announced to recall millions of car GPS navigation and offer free battery exchange which because of the battery overheating. Thereafter, the China manufacture begins to exchange the GPS navigation for some models in China market. What the influence will the overheating battery bring? The answer is that the signal will be very poor, and more serious could cause explosion and cause fire. Are you still daring to use these products? Those common electronic products such as computer and cell phone, the battery use length is very important for the safety. Because many consumers seek to buy those cheaper products with poor quality, the battery products of the navigation products is always worrying.

2. Hidden danger two: The piracy map.

According to the country’s regulations about car DVD player GPS, the products must use the identified electronic map by the national specialized agencies. But those GPS navigation with standard electronic map is often very expensive because of the huge investment.

3. Hidden danger three: The big radiation.

When choose a car DVD player GPS navigation, do not just simply consider the cost. Last year, the AQSIQ aimed at the GPS navigation with a large-scale spot check. And they found Flyaudio, Roadrover and some other famous GPS navigation brand’s radioactivity range is out of the standard level. In fact, there are many less known car GPS player navigation in the market and because of too much radiation harassment they are disqualification. Radiation disturbance means the intensity of electromagnetic wave that launched by electronic products is beyond the regulation limitation. Generally, if the intensity of electromagnetic wave is too high, the users may get headache, insomnia, memory deterioration and some other negative effects after using the product for a long time.


In China, the traffic laws does not affirmative disclosure the car DVD player GPS navigation and car audio products is forbidden. So, the operation frequency is a little high in our country. In act, electronic products that connected with our life such as cell phones, laptops and TV have potential dangerous just as the navigation system. Because of the improper use habits, the dangerous situation can not be avoided. If we want to make the car DVD navigation become a safe product, the first thing we need to do is that let the users operate the device in the right way, then in this way, the dangerous probability can be reduced. When use the car DVD player GPS navigation, safety comes the first, so the user must carefully read the disclaimer and precautions for use first when starting up.

This offers an additional source of entertainment to the travelers. There are also some cars in the market that are operated by a computer. In such cars, the passengers control all the commands with only a push of the button. This really proves that technology is affecting the effectiveness of cars.

Men are the major car buyers in the United States. They buy about 63% of all new vehicles sold. And while men tease women about being emotional, impractical, and intuitive, these roles are often exchanged in the purchase of automobiles. Here it is the woman who is makes logical and practical choices while the man often bases his selection more on vanity desires than practicality.Consider for instance, engines. The larger the engine, the more gas required to operate it. Therefore, to realize fuel economy, one needs to purchase a car equipped with a small engine. But men don’t like to do this. In spite of fuel costs, men tend to opt for the big engine. As one man stated, “Four cylinders is only half an engine.”

This is applicable with any vehicle as no car parts possible survive during the entire life time of a car. Also is the case when you have a rough ride on the highway or a small crash which will result in a broken bumper or a damage of your vehicle axle. In any of the case you have to replace your damaged Audi car part with a new Audi car part. Mostly in the situation you will be searching for an Audi car part dealer to buy the necessary Audi car part.

Audi has an eye-catching external looks and it has been endorsed in many rallies, sports car racings and for traveling. Audi car parts consist of hundreds of amenities mostly found in luxury cars or roadster. The latest models launched by Audi are equipped with services aimed to beat Mercedes Benz C Class.
