We integrate into the factory backup camera for this 2010 Mazda CX-9!
The factory radio in these Mazda's internally provides 6-volt power to the camera, and when removing and replacing you have to create a new 6-volt source for the camera to operate.
This 2017 Dodge Journey gets a OEM Backup Camera
We got his setup with installation and activation for his factory 8- inch radio without ever taking a trip to the dealership!
