Remove Dome to access rear view mirror

Hello,

Can anyone tell me how to remove the covers around the mounting for the rear view mirror or to remove the dome itself? I am trying to hard-wire a dash cam and this seems a lot better than trying to run the cables all the way down to the center console 12v socket.

The trim appears to all be pretty tight so I didn't want to pull to hard on anything...no obvious way to remove.

Help!

M

I found this video for a different model but its the exact dome (and this worked). Now I just need to find a switched 12v source. The thick black red wires appear to be always on (it was on for at least 4 hours after I shutdown and locked the car)

Thanks. I was able to complete this using the video I linked to.

Also - I found that pin 1 (white) in the connector that heads off towards the mirror is a switched 12v source that is on only when ign is in 1,2,3
