trafic service help

Hi can anybody help me with getting hold of an owners manual and service interval book for a an 06 Trafic please. Also I've had some very conflicting advice/reports re the engine and gearbox. I've been told that some models have a timing chain and others a cambelt - one person even told me that the chain types also have a cambelt but that doesn't seem right. How can I find out what mine has? I've also been told that the 6 speed boxes don't suffer from the tight bearings that cause the 5 speed to fail. Is this true? Any help or advice from those of you in the know would be truly appreciated. Thank you.

Simon.
