Are there any remova instructions?

I have an internal erro on my Almera Tino display in the dash board, Nissan want to charge me £87 per hour to "investigate" the problem, I have purchased a new Radion form an online source. I cannot find any information of how to remove all the dash trim to be able to get it out. Any help or advice out there to help?
