The history of autoradios

The development of the basic technologies of recording, sending and receiving audio signals via radio waves is based on various international inventions of the 19th century. The first commercial, free-to-air radio broadcasts are also broadcast in Germany in the early 1920s.
As early as 1922, the first automobile models were equipped with autoradios in the USA and England. In the following decades, with the growing interest in broadcasting, the development of new autoradios and corresponding technologies is also being promoted. Initially, the equipment of a vehicle with a radio is still a very costly decision. The proportion of an autoradio in the total cost of a vehicle in the 1930s is still up to 15%. In addition to the continuous improvement of radio reception, in Germany via ** Ultrakurzwelle (FM) **, individual manufacturers begin in the late 50s and 60s With the integration of playback devices which should take account of the driver’s desire for an individual design of the music program. In 1968, for example, the first cassette radio was released. In 1983, for the first time, a CD player was integrated into an autoradio.
A further step in the direction of today’s equipment is the use of a second receiver in 1987, as the basis for the introduction of the Radiadata System (RDS), which is still in use today, which allows the processing of traffic announcements and the transmission of broadcast names and other information .
With the nineties, the functions of the autoradios are decisively expanded. The latest development, since the 2000s, in addition to the possibility of playing modern audio formats such as MP3, the integration of various interfaces For numerous other multimedia and communication devices.


Factory equipment vs. Retrofitting

As a rule, new cars from all manufacturers and classes are factory-equipped with an autoradio and a basic equipment of necessary loudspeakers. Higher-quality systems are usually offered as an optionAutoradio music-at-the-ride special accessories or are part of individual vehicle special editions.
In the 1980s and 1990s, the trend was growing, especially among young drivers, to replace the inadequately perceived factory-side autoradios with more powerful models from the accessory trade. This trend has created an active car hi-fi scene, which is still active today, which deals intensively with all areas of the feasible in the field of sound optimization and knows hardly any limits in terms of volume, effort and costs. In addition, it became possible to make additional comfort features and functions usable in vehicle classes for which no adequate offer was available from manufacturers.
The basis for all efforts to adapt the sound system of a vehicle independently to its own requirements is the international standardization of basic construction criteria of a commercial radio station. With the ISO 7736 standard from 1984, for example, the installation dimensions for autoradios are defined. There are still two different types of construction:
1 DIN Autoradio with the dimensions 182 mm x 52 mm and a depth of the installation at least 160 mm.
2 DIN (also double DIN) -authoradio with double, ie 104 mm installation height.
Autoradio-DIN dimensionsIn addition, standardized connections for loudspeakers as well as other necessary elements and functions such as loudspeakers, power supply, switching on and off of the radio via the vehicle ignition, electric antennas etc. were introduced and also certified. This took place decisively in 1992 with the ** ISO standard 10487 **. This standardization made it possible to connect the car radio to the majority of manufacturers with a minimum of effort and at most the purchase of an additional plug-in adapter. In addition to this are standardized standard sizes for installation loudspeakers, which make it possible to replace simple loudspeaker systems with high-quality models.

Modern Autoradiovarians – advantages and disadvantages

In recent years, car manufacturers have increasingly recognized that a high-quality sound system can decisively influence a purchasing decision. As a result, efforts have been made to conduct tests on the factory sound systems so that they can satisfy even the most discerning music lovers and can score with maximum functional range and ease of use. This includes the use of high-quality components, such as radios and loudspeaker systems from renowned manufacturers, which, however, are generally provided with branding by the vehicle manufacturer. All elements are optimally matched to the requirements of the acoustically demanding interior of the vehicle and coupled with other vehicle systems.
Authoradios are increasingly integrated into the interior design and are only seldom visually comparable to the known designs. Although the built-in dimensions are generally in accordance with the ISO standards mentioned – most of the car manufacturers choose radi models in the 2 DIN format – the front panels are individually adapted to the vehicle design, and control elements are occasionally arranged or stored separately.

It is not always possible to replace such a workplace authoradio by one of the accessories trade. Already the expansion can involve a lot of effort, since under certain circumstances complete veneer elements must be removed. In addition, these blinds are adapted to the factory’s authoradio in such a way that, after the replacement by another model, gaps remain, which must be covered by suitable accessories from the accessory trade. If the vehicle interior is color-coded, additional effort is required in order not to impair the overall image of the vehicle interior. Particularly in the case of exotic vehicle models, the procurement of such building blocks is a major challenge.
