Pioneer takes you on a journey of sight and sound. A top maker of consumer and commercial electronics, Pioneer sells car electronics (stereos, speakers, navigation systems) to retailers and automobile makers. The company also sells other audio and video equipment to consumers (DVD players, stereo systems) and business customers (factory automation systems). In addition, its US-based Discovision Associates (DVA) licenses optical disc technologies. Pioneer has about 35 manufacturing facilities worldwide. The company -- Pioneer Kabushiki Kaisha in Japanese -- was the first to offer customers the laser disc, car CD players, and car navigation devices that use a satellite-based global positioning system (GPS).
