Suction-cup the camera onto the windshield. I place mine on the right of the rear-view mirror, which keeps it out of my sight but with a good view of the entire road.

Start at the end that is connected to the camera, and tuck it into the top headliner. There's plenty of space between the headliner and the glass to fit a cable or two. You should be able to stick it in their with your fingers, but a small plastic tool might help secure it. Avoid using anything sharp (no screwdrivers, knives, etc), as the materials in this car are very easy to scratch.

Bring it down the pillar. It's near impossible to get a photo of it, but you're going to stuck it down the support beam towards the dash. Be very careful not to tuck the cable behind where the side airbag is, as we certainly don't want a cable to impede its operation. I left mine sticking out a little bit for that portion, which isn't noticeable.

Bring it around the gap on the dash

Tuck it into this panel that covers the side-window HVAC vent

And out the other side, then tuck into the gap between the glove compartment and the pillar

Route the cable through the natural gap towards the weather striping on the door

Tuck it into the weather striping gap. It should fit in there well, but you may need a blunt object to tuck it in with.

Wrap it through the platform on the bottom of the glove compartment near the air intake

Bring it back around to where the outlet is. I taped the connector in place, but you could also just leave it on the floor or let it dangle off the plug

Optional: I used a splitter so I would still have an available 12V outlet for other accessories.

No cables obscuring the view
