Interior was updated in 2006, this tackled one of the main issues by moving the hazard warning switch as it was fairly easy to knock on with your elbow. Other changes were nicer knobs, different door cards, Illuminated ignition switch, illuminated steering wheel controls and a few other minor things. Exterior changes included new bumper with slightly different shaped headlight washers, uprated headlights, rear LED's and Rays are standard fitting from 2006 onwards. Also, Nissan engineers managed to add an extra 70 kilos to the weight . Differences are neither night and day or barely noticeable...somewhere in between I'd say
