1. Remove the upward facing screws above the radio, beneath the heater vents in the centre of the dash.
2. Remove the Ash tray and there are two screws behind there also.
3. the plastic panel should now pull off, the heater vents will come with it, be careful to remove the connector for the Hazards and the Heater rear window switches in between the air vents.
3. there are 4 screws behind this which hold the radio onto the dash. remove these
something like that, sorry about that, was a bit tipsy last night
I removed the plastic panel
today. Very easy took 2 mins. I need to buy a harness that goes between the Nissan connector and the ISO one on the Sony header.
