How to display av signal on Car dashcam?

[blueknife]

I have rear camera with AV signal output, so I can display it on external LCD with AV input (like 1st picture)
But this LCD look very ugly. I want to use a IPS Screen dashcam (like 2nd picture) to display it. Do we have any 4" IPS Dashcam with AV input?
Do I have any otherway?

can't say I've seen any dashcams that have AV input, always an AV output, some GPS units have AV input, maybe another option for you

I think AUX input is ok
