The Gosound is the industry's first stand alone auxiliary input for Hyunday.BMW.HONDA.NISSAN vehicles with Alpine 6 CD chnager . The Go sound interface will allow up to two auxiliary input sources to play through OEM radios that are equipped with the 8pin harness. The Gosound was created to provide a fool-proof method for supplying a direct audio input for multimedia installations. This plug-n-play solution surpasses FM modulation which is the current method of introducing audio in these systems. Selecting an input source is as simple as pressing the CDC button on the radio. The head-unit can toggle between all the possible sources as if they were factory installed, displaying CD, AUX1, AUX2 or whatever source is selected.
