New Car Audio installation in Land Cruiser

Hello good.
I have a problem in trying to install a new radio in my Land Cruiser 1999. This comes with the 56808 radio and I want to change it for a DVD and GPS player, my problem is that I must connect the New and I do not know which of the cables that came out of the previous one (those that are standard), are 14 cables of different colors I ask you to please you can illustrate me. THANK YOU
