Fourth Gen Sentra Stereo Wiring Guide 2000–2006

The next generation of Nissan Sentra forgoes the single DIN layout and uses a customized center console. This makes for an aesthetically pleasing Sentra radio but this change does require that you use a stereo install kit.

Without the right install kit, you will have a hard time installing your Sentra radio.

To access the mounting screws you will need to remove the face of your center console. Once you have the climate control vents removed and the plastic panels around your climate controls, you can take out your factory Sentra car stereo.
