Nissan 350Z

Production years 2003 - 2010

The Nissan 350Z have a facelift in 2006 which affects the radio fascia. It is a very minor difference in the fascias needed from the pre facelift to post facelift models.

The easiest way to tell if the car is the older or newer model is to look at the styling around the gear stick and the location of the hazard switch.

In the picture above you can see the different styling around the gear stick and the position change of the hazard switch.

The left image is of the 2003 - 2006 model, the hazard switch is positioned further back near the handbrake, the 2006 - 2010 model on the right has the hazard switch further forward on the dashboard located between the gear stick and below the climate controls.

Bose integration.
Most 350Z cars have factory fitted Bose audio systems. New equipment like head units and handsfree kits can be easily added to this system using high to low level adapters. The original head unit supplies the audio to the amplifier via a low level signal.

When fitting a new head unit, sometimes the audio sounds quieter than expected, this is normally caused by the new head unit having 2V preouts. Head units with 4V preouts will provide better audio. Another way to get better audio is to use an adapter lead for a non amplified car, use the ISO speaker outputs from the head unit and run the audio through a high to low level interface, this will give the best audio quality.

The Bose amplifier is turned on by a 12V switch signal.

This diagram shows the position of the amplifier turn on (AMP ON) pin. Use the 12V switch output from the new head unit (blue/white wire) to turn the amp on.
