I'm pleased to introduce Dongar Technologies' plug-n-play dashcam adapter!
How does it work?
This adapter shares the 12V source powering your rearview mirror. A step-down switching regulator with over-current protection provides 5V to a typical USB port. This adapter functions only when your ignition is switched on. If your dashcam has a power-on mode, it'll start up automatically with your car.
Is my vehicle compatible?
This adapter will work with modern Mazdas with Homelink autodimming mirrors. Unfortunately it is not compatible with 'frameless' mirrors on the 'Signature' trim, but a version of that is in progress! Recent customers have installed these on MX-5, Mazda 3, Mazda 6, CX-5 and CX-9!!!
How do I purchase one?
A limited quantity of these adapters are available for direct sale for $24 shipped via USPS first class. These will be made-to-order and need 2-3 days processing time to ship out. Each adapter sold directly on Mazdas247 will be individually tested for fit and function and has a 100% money-back guarantee. It is also available on Amazon.

I want to say how pleased I am with this adapter. Installed on my 2016 GT. Running a Rexing V1 dash cam it works perfectly. Saved a boat load of time and effort over hard wiring the unit. The camera powers on when the vehicle is started and powers off when vehicle powered off. Works like it should. Highly recommend.
I will echo Hookman49's sentiments in that this was the tidiest solution for me when I mounted a dashcam on my windshield (2016 CX-9 Touring). All connections are up by the rear view mirror using the existing power. No routing wires, no worrying about the correct pinout - just plug and play!
