I just got a 23 CX-30 and want to install dashcams for the new car.
Normally I see people putting the wires inside the gap between the roof and the A pillar. This works if there is no airbags nearby. However, from the collision test video here https://www.iihs.org/ratings/vehicle/mazda/cx-30-4-door-suv/2020, it seems like that the covering panel of A pillar will pop out when a collision happens. If the cable is put inside the panel, the cable itself may pop out also and hurt driver/passengers.
Another headache is for the rear camera that usually requires a wire put into the top side panels. But CX30 has curtain airbags also.
So the only way for CX30 to have a dashcam is to buy those integrated ones? Amazon sells one at above $200 and it takes power from the electric port of the sunroof I believe. How is everyone dealing with this issue?
I just bought a dashcam just yesterday, thinking of my plan of attack with installing on my CX5, as I bought a rear dash cam, too. I think you either need to compromise with dangling wires out in the open, a 12v system, accept your fate with putting the wires close with these side airbags, which many seem to do tbh. Or you can fish the entire wiring system down the floor, or route the wires near the floor instead of above like many do. I think you still have to fish it through some areas through some of the pillars, but the exposure of much of the wire, in the event of a crash, to you would be near your legs, rather than your neck, I guess.
Edit: I guess still you can do a proper wiring around the airbags, but you’d need to remove panels completely so you have proper access to the wiring behind the panels and airbags. Maybe buy some zipties, too. Also this is why there’s dashcam installers that can professional install dashcams and other stuff for you. I don’t think there’s much risk to routing wires with the airbags around. As long as the car is parked and completely off, the airbags shouldn’t deploy randomly.
