when did they first put radios in cars
Vehicle audio In 1930, the American Galvin Manufacturing Corporation marketed a Motorola branded radio receiver for $130.[5] It was expensive: the contemporary Ford Model A cost $540. A Plymouth sedan, "wired for Philco Transistone radio without extra cost," is advertised in Ladies' Home Journal in 1931. In 1932 in Germany the Blaupunkt AS 5 medium wave and longwave radio was marketed for 465 Reichsmark, about one third of the price of a small car. Because it took nearly 10 litres of space, it could not be located near the driver, and was operated via a steering wheel remote control.[6] In 1933 Crossley Motors offer a factory fitted car radio.[7] By the late 1930s, push button AM radios were considered a standard feature. In 1946 there were an estimated 9 million AM car radios in use.[8]
