What about Polaris 287924, lets see here



Form and fit are perfect. The radio fist nicely in the dash with no cutting. All the wiring is with the radio and no cutting id involved with wiring either. Polaris 287924 antenna is actually working OK. I can pick up all the local stations in my area. The Bluetooth connects to my Samsung Galaxy five easily and has a range of about ten feet. The speakers are the weakest link I believe. they're tinny and have little to no bass. The place for the speakers takes up little space in the dash but music is hard to hear when your traveling down the road. The biggest con with this unit is the weak sound but this may be fixed with a pair of speakers mounted in the back of the cab. In 1930, the American Galvin Manufacturing company marketed a Motorola branded radio receiver for $130. It was expensive: the modern 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 five medium wave and longwave radio has been marketed for 465 Reichsmark, about one 3rd of the price of a small car. Because it took almost ten litres of space, it couldn't be located near the driver, and has been operated via a steering wheel remote control. In 1933 Crossley Motors offer a factory fitted car radio. By the late 1930s, push button AM radios were considered a regular feature. In 1946 there were an approximated nine million AM car radios in use. An FM receiver has been offered by Blaupunkt in 1952. In 1953, Becker presented the AM/FM Becker Mexico with a Variometer tuner, just a station search or scan function. In April 1955, the Chrysler company had declared that it was offering a Mopar model 914HR branded Philco all transistor car radio, as a $150 choice for its 1956 Chrysler and Imperial car models. Chrysler company had decided to discontinue its all transistor car radio choice at the end of 1956, caused by it being too costly, and replaced it with a cheaper hybrid transistors and low voltage vacuum tubes car radio for its new 1957 car models. In 1963 Becker presented the Monte Carlo, a tubeless hard state radio, with no vacuum tubes. In 1964 Philips launched the Compact Cassette, and in 1965 Ford and Motorola jointly presented the 8-track tape in car tape player. In successive years cassettes supplanted the 8-track, and improved with longer play times, better tape quality, auto reverse, and Dolby sound reduction. They were liked during the 1970s and '80s. While the CD had been on the market since 1982, it was in 1984 that Pioneer presented the CDX-1, the world's 1st car CD player. It was recognized for it is improved sound quality, instant track skipping and the formats increased durability over cassette tapes. caused by the capability that allowed drivers and passengers to change up to ten CD's at a time, car CD changers started to get popularity in the late 80's and continuing during the 90's. Stock and aftermarket compact disc players began coming out in the late 1980s, competing with the cassette. The 1st car with an OEM CD player was the 1987 Lincoln Town Car, and the last new cars in the American market to be factory equipped with a cassette deck in the dashboard was the 2010 Lexus SC430, and the Ford Crown Victoria. From 1974 to 2005 the Autofahrer Rundfunk Informationssystem has been used by the German ARD network. worked on jointly by the Institut fr Rundfunktechnik and Blaupunkt, it indicated the presence of traffic announcements through manipulation of the 57kHz subcarrier of the station's FM signal. ARI has been replaced by the Radio Data System. In the 2010s new ways to play music came into competition with the CD and FM radio like internet radio, satellite radio, electrical connectors and Bluetooth connectors for movable media players, and in dash slots for memory cards. And the car head unit became more and more important as a housing for backup cameras, navigation systems, and displays for smartphones like CarPlay, Android Auto, and MirrorLink. Some car manufacturers have their own systems for syncing the car with smartphones, for example: BMW help, Hyundai Blue Link, iLane, MyFord Touch, Ford SYNC, OnStar, and Toyota Entune.
