Mercedes Viano Manual

Hello everyone, first of all greetings to everyone since it is my first message.

Then I would like the radio that brings from Sarie my Mercedes Viano and set up one of those multimedia that I am still looking at them, the fact is that as a chiro put the rear camera and the TDT and those pijadas I needed to see if someone had a manual to be able to demontar, the radio in question, but at the same time plastichitos and areas of the board that I suppose I will have to disassemble me Greetings again and thanks in advance.
