ISO Standard for Car Radios

A standard for the audio connections of car radios has been generated in order to avoid having every car manufacturer devise its own solution to this common and recurrent issue. This standard has now been adopted by the International Organization for Standardization (ISO). The mechanical construction, dimensions and shape are clearly specified, at least in principle. Here we have to say ‘in principle’ because some manufacturers cannot resist the temptation to arrange the signals on the connectors according to their own ideas.
