This page is for JVC head units only. 

Why is the JVC DCI different?  Because the head unit operates differently than other head units.  For example, on most radios the button on the factory remote that changes MP3 folders also cycles through the radio presets.  But on JVC they paired "Next radio preset" with "Previous MP3 Folder" which sounds silly to me, but that's the way it is.

In the charts below, functions that are different than the "standard" DCI are shown in red text.
