Kenwood tested out the double DIN in-dash navigation market with the DNX7100 in early 2007. Upon discovering its success, Kenwood continued its pursuit for supremacy in the car audio industry with the introduction of three 2008 DNX Series in-dash navigation: the DNX5120, DNX7120, and DNX8120.
All three of these units feature a built-in Garmin GPS navigation system with over 6 million points of interest for maps of the United States (including Hawaii), Canada, and even Puerto Rico. In addition, the DNX units could give users voice guidance of street names and upcoming turns. The in dash head unit could also receive XM live traffic as well as weather information and display them on the screen
