NEED HELP ON HOW-TO remove H2 nav/stereo console

[icecreamed]

Hello!
I have a 2006 H2 w/ a Pioneer AVIC-Z1 installed last year.
I just noticed that my navi does not go into night mode...
and so it is BRIGHT AS HELL when I drive at night.

Also, my TV-tuner came off-line.
I also want to hook up a back up cam into the navi,
even though I already have the rear-view mirror cam.

I want to do this myself since best buy is charging me $200 for install only.
And I do not want to get ripped off anywhere else.

Does anyone know how and have pics as well?
I have been searching on-line for 2 days now and have found nothing.

Thanks!
