1995 Nissan Bluebird Stereo Installation - HELP!!

I'm stuck and it's doing my head in!!

I recently bought a car CD player and speakers for my recently bought 1995 Bluebird. I've downloaded the manual (which is extremely vague) and now I'm removing the front instrument panels in order to replace the old CD player. I've removed the glove box, as well as some panels down near the floor. There are no more visible screws or bolts to remove!! The manual is really crap and it is no longer of any use.
Can anyone help?? Should I pay extra and just get a pro to install it? any idea how much this would cost?

Thanks heaps for your help-
Hayden

this is a problem....

I've sorted it out- there was a panel which just popped out. I was afraid of pulling it because I didn't want to break anything....

if endoubt- pop it out!

cheers
