What is the head unit. Native head unit

The modern car is stuffed with all sorts of electronics, aimed at improving safety or creating comfortable conditions while driving. Not every driver knows about all electronic devices, as well as the tasks they perform. The only exception is, perhaps, only the head unit. Under this term, the multimedia system of the car, which performs many functions familiar to us, is hidden.

In this article, we will discuss in detail what multimedia systems are, what capabilities modern models from different manufacturers have.

Multimedia system - the central element of the car interior

From a long time in the cabin of any civil car, the central place was occupied by the radio tape recorder. There are a lot of devices on the dashboard, but it was with her most often had to deal. Previously, its capabilities were limited only to playing FM-radio or at best audio cassettes and disks. What significant changes have taken place?

Now full-time head units are full-fledged systems capable of performing many different functions. In fact, with their help, the car turns into a full-fledged entertainment center, and in some cases - into a computer that controls the performance of the car.

There are several main groups of tasks that the head device is designed to perform:

• Entertainment (audio and video).
• Control of various car systems.
• Orientation on the ground (satellite navigation).

Given that the requirements for the current vehicles are constantly growing, the complexity of traditional multimedia systems is also becoming higher.

Appearance and location features

Traditional car radio was almost invisible in the cabin - they did not take much space, and control was carried out with just a few buttons. Now the situation began to change dramatically. Most often, the manufacturers themselves create a head unit for a specific model of the car.

There are several characteristics of such a device:

• The central place on the instrument panel.
• Stylish and attractive appearance.
• A large number of different buttons or controls.
• The presence of an LCD display, etc.

This suggests that the standard head units become much more complicated and functional. Accordingly, their significance increases.

Features of modern multimedia systems

Different models of similar devices differ not only in their kind, but also in their capabilities. Obviously, Toyota's head unit will differ from those that are installed on cheaper models. Although now all manufacturers are trying to reduce this gap, and this contributes to the rapid development of various technologies.

If we take for example the most advanced version, then the head unit has the following capabilities:

• Radio.
• Play audio from various media (CDs, flash drives, etc.).
• Video playback with output to the main screen (or connected separately).
• Satellite navigation (GPS and GLONASS).
• Control of various automobile systems (with data output to the main screen).
• Quick control with the help of the touch screen by various devices (lighting, air conditioning, driving modes, etc.).

Established head units become a kind of additional instrument panel, designed to significantly facilitate the life of the driver and passengers.

Navigation is a popular and demanded feature

As already mentioned, the requirements for cars are constantly increasing. In this regard, and the staff head units become more complex. Most often this leads to the fact that they combine the capabilities of various devices, including the navigator.

Traditionally, the main functions include the following:

• Demonstration of the map of the area.
• Route planning.
• Calculation of speed and time of movement.
• Providing up-to-date information on traffic congestion (in extended versions).

At the moment, the devices are equipped with sensors for both GPS and GLONASS. In automatic mode, they determine the exact location and provide relevant information to the main screen. The advantage is obvious: there is no need to purchase a separate navigator.

Third-party multimedia systems

In our time, head units of Toyota or other advanced automotive brands are quite common. However, owners of more simple machines from the budget price category are deprived of the opportunity to enjoy all the advantages of such devices. The question arises as to whether it is possible to install such systems separately.

Yes, now in a huge range are sold models from third-party manufacturers, and the installation of the head unit Produced on almost any car.

Where can I buy?

At the moment, you can find everything you need in specialized car shops, and also order online. On sale are devices from different manufacturers, differing in their capabilities and dimensions.

What to do after purchase?

It is enough to turn to a service center or a workshop that offers installation services for the PG. Experienced masters will perform all operations quickly and efficiently.

Acquisition Features

For your car, you should always choose only the best. And it is advisable not to overpay extra money. Therefore, the issue of choice must be approached very carefully, not missing a single detail.

When buying, pay attention to specific technical parameters:

• Functionality.
• A set of built-in elements.
• Inner memory.
• Availability of various connectors and modules for wireless connection (USB, Bluetooth, Wi-Fi, etc.).
• Requirements for installation.

Specialists recommend to formulate specific requirements for themselves, so that later it would be easier to choose this or that model. The cost of such equipment varies in a wide range, so it is better to immediately solve all the available issues.

Compatibility of the multimedia center with this or that model of auto

One of the main points is the compatibility of equipment with a specific model of the car. In other words, when choosing, each one asks whether it will be possible to install a particular device on his machine.

If you are, for example, the owner of Chevrolet, then it is worth choosing the appropriate head unit "Chevrolet". Experts recommend studying the list of compatible or recommended models. Usually such information can be found on the manufacturer's website or in the description of a specific device.

Although there are universal models that fit in size and other technical characteristics to almost any machine. The disadvantages of such versions are usually:

• Limited functional.
• Possible complications during the installation or during further operation.
• Need to use a special framework (for a strong installation and hiding gaps).

It must be remembered that, for example, the specialized head unit "Nissan" will always be more functional and quality than the universal models on the cars of this brand.

Multimedia centers based on Android OS

In the last 2-3 years, among the motorists are gaining popularity various devices based on the mobile operating system Android. A large number of different gadgets are produced on the basis of this OS. In addition, the system itself becomes more functional and convenient.

To date, the original head unit Android Is the most advanced and innovative solution for various cars. It has not only a rich functionality, but also a thoughtful management system, a pleasant interface and the ability to independently expand the capabilities of the device. This is what attracts such equipment:

• Extended set of functions.
• Simple and convenient operation.
• Compatibility with various mobile gadgets.
• Possibility of self-installation of additional software.

Many motorists own smartphones or tablet computers on the basis of this system, so no complications in the work does not arise.

International standards for dimensions

Currently, there are a number of international standards for this type of device. The most important is the standard, concerning the dimensions, because this largely depends on the further installation.

Now all companies in the production take into account the following standards:

• Eight-pin connector type ISO 10487 (for connecting PG with the main electronic auto systems).
• The size of Single DIN ISO 7736 is 178 x 53 mm (it is common in some countries of Europe and South America).
• Size Double DIN - 178 x 106 mm (distributed in North America, United Kingdom, Japan).

When choosing a device, you should focus on these standards - they will help you choose the most suitable option.

The ratio of auto brands and models of multimedia devices

Now GU is not always represented by the same brand as the car. Automotive concerns often abandon their own designs, concluding profitable contracts with third-party manufacturers. That is why effective and high-quality electronic equipment can be sold under other brands.

On the basis of partnership relations between companies, compatibility of models can be traced:

• Mark Levinson for the "Lexus".
• Bose - this is the head unit "Mazda" and "Cadillac".
  
• Harmon Kadron - the device for "Mercedes", "Saab", "BMW", "Subaru", etc.
• Rockford Fosgate for Mitsubishi.
• Sony for Ford cars.

Famous electronics manufacturers such as Sony, BBK, Panasonic, Mystery, Philips, usually produce more versatile models for popular cars in the budget and mid-price range.

But in this case, you should not forget about the functionality of the GU. Simple models do not always have the necessary set of capabilities, in some cases such equipment is considered morally obsolete. Therefore, we have to look for a certain compromise, so that soon after the purchase there is no need to replace the head unit.

In some cases, the same GU may be sold under different brands. This situation is due to the fact that car companies conclude special contracts with electronics collectors.

Manufacturers of universal head units

Universal models are in stable demand, because they allow you to bypass many restrictions and install the necessary equipment on your machine. Nowadays, there are several of the most famous brands. Among these specialists and ordinary consumers include the following:

• "Phantom" (Phantom).
• "RedPower" (RedPower).
• "NaviPail" (NaviPilot), etc.

The first brand is considered to be the most widely held, it occupies a leading position in Eastern Europe. The company offers inexpensive and quite interesting solutions for a wide range of consumers.

The second company specializes in the production of devices running mobile operating systems Windows and Android, so its products are of considerable interest.

The third trademark has proved itself from the positive side, because it offers really multifunctional equipment, which is installed even on BMW and Mercedes.

Conclusion

When choosing the standard head units for a vehicle, it is necessary to take into account many aspects, primarily functionality and compatibility. It is very difficult to do this on your own, therefore it is recommended to pay attention to the recommendations of manufacturers and the advice of experienced users. Then it will be possible to select a multimedia center that will significantly expand the possibilities, increase comfort during the movement and safety on the road.

Qualitative models are found on sale in sufficient quantities, and owners of new cars often make a decision to replace their standard GU with a third-party model, because it is much more convenient and practical to work with. This is especially true for devices based on the mobile operating system "Android".
