I have been looking into getting a dashcam for a while and I'd like to hard wire it in so it's working, but automatically. Of course I'd like to get something as small as possible so it can be hidden and not an eyesore. There are a lot of models with LCD screens that are good, but even smaller ones without. I've read several poor reviews about the ones equipped with wifi and how unbelievably slow they are. I was wondering if anyone has, or knows about, using the multi-function display as a dashcam screen. I have a back up cam and was curious if there are any other inputs for something like a dashcam or if I can use some sort of video splitter or other wiring jack.
