I'm getting the BlackVue DR3500-FHD dashcam, this is a very affordable dashcam which comes with parking mode. This mode is probably the only reason why I want this model. I don't wish to hardwire the dashcam. Question is, will parking mode work in my 2016 Civic EX if it isn't? I'm not sure of the 12V outlet still draws current if the car is off.
