08 cvpi icop help

So I have the icop 20/20w installed in place of the factory radio and the front/rear cam was delivered yesterday. Does anyone here know how to #1 remove the headliner and #2 mount the bracket to the roof under the headliner? I have the wires run for the brain but need to run cam 1, cam 2, and the internal Mic wire. thanks in advance for any help.

Remove the headliner or just drop it?
To drop it you need to:
- remove A, B and C pillar interior covers
- remove push pins holding up the back
- remove coat hooks
- remove visors and their clips up front

With all that out, the headliner will drop.

It's easier to pull the headliner out with the front seats out but can be done with the seats in. It's easier with the steering wheel out but can be done with it in as well.
Lay both front seats all the way down and you can maneuver the headliner out the front passenger door, you'll need to bend it a little.
