I've just used the Dongar connector to fit a Nextbase dashcam. This is a "traditional" dashcam, but the Dongar plug and socket allows you to draw power from the supply to the auto dimming mirror, and avoids the hassle of routing cable from the fusebox and behind the seals around the door frame. It's an easy fit, nestling behind the plastic shroud behind the mirror. Unclip the power supply, insert the identical male plug into the female receptor, and v.v with the other plug, and you're left with a USB power supply for any dashcam that uses a USB supply. My Mazda is the 2023 Homura. NB Dongar is supplied from USA and cost about £38 including shipping. NBB it needs the 10 pin plug, not the 5 pin plug recommended by Dongar's web chat facility. Best to unclip the shroud first to see your power supply behind the mirror.
