Fishing wire overhead

I will be mounting a dash camera on the rear view mirror bracket and need to get engine-on 12v to it.

Has anyone done this?

Running wire from the cigarette lighter and up behind the inner door seal along an A-pillar is easy enough.

Has anyone fished wire behind the ceiling fascia WITHOUT removing it? Say, by removing the overhead console and a sun visor in order to use those areas to fish from.

In the overhead console, there are three screws easily accessible once the sunglass holder is opened. After those the only screws that hold the console, or are there others? How to access?

Thanks,
