You are easy able to route wires around the windscreen.
If you start at the top and dead center then the wire go up above the headliner, here you should be able to just push the wire up above the headliner, this should be totally tool less.
Then you get to the A pillar, and here you often have to pry off the decorative plastic trim, some times a single screw is used to hold things in place, but often the plastic just click on and off with a little force.
Now in there you want to be careful with any airbags that might be located there, but if you can get in behind the airbag or at least trail the wire down close to the windscreen glass ( airbag should deploy in the other direction.
Some cars you don't even have to move the plastic trim pieces as there is a gap you can just press the wire into.
When you then reach down to dashbord level there is 2 routes, one is strait down at the base of the A pillar, i can do this with my Cheap Small Suzuki car.
This off course mean that i will have to start in the other end with the cigarette plug/adapter as it is too large to thread thru the little gaps, and the mini USB plug in the other end of the wire go thru very small holes.
Starting at the cigarette plug is actually the right place to start, so forgive me for explaining in reverse for some strange reason.
Anyways back to the power wire, if you dont have a gap at the base of the A pillar you can go down thru and down below the dashbord, then you are often able to route the wire down between the rubber door seal and the dashbord side, and then also down and below the dashbord.
Now that you are down below its just a matter of routing the wire across the foot well, there should be stuff below the dashbord to zip tie or tape the wire to so its out of the way, and then its just a matter of routing the wire around to the cigarette socket on your center console or maybe thats in the console between the seats.
You can power any 5 volt dashcam using a USB power bank, but thats no optimal way to do it.
One day you have forgotten to charge it or just down right forgotten it, and who care its just a short trip to the store down the street, and then murphys law kick into action and that short drive was just where you needed a recording.
So either the regular route using the provided adapter in the cigarette plug, or you can piggy back on a fuse in the fusebox for the same result.
This is my old setup with just one 5 port USB cahrger in the glove box, this have since become too little so its expanded a lot.
In the video you can see the plastic trim pice from my A pillar lying on the dashbord.
Since then i have expanded my power grid to be more suitable for a dashcam tester, so now i have the following connections at hand.
In glove box one of those 3 way cigarette adapters i call garbage in the video, it also have one 2 amp USB outlet.
I then still have the 5 way USB charger ( 2 X 2.4 A + 3 X 1.0 A outlets ) and i have also added another 4 way USB charger with 2.4 A on all for outputs.
I have then piggybacked into a 10 A fuse in my fuse box and installed the other 3 way cigarette splitter in the boot of my car.
more install camera videos.
A little more advansed install tapping into fuse box for install of a Battery discharge preventer you will want if you plan on using parking guard while the car is parked.
but fear not a little offset is no big deal with the wide angle lenses dashcams use.
