That Kenwood unit says it is 7" "VGA" which is normally only 640*480 resolution. Reading further down it is however stated as 800*480 which would fit the aspect ratio.
RNS-D is 5" by comparison and IIRC half VGA resolution at 320*240.
Unless you're going for an expensive iPhone-type display you won't get 1080p, and there's probably no point anyway given the maximum width and viewing distance of a driver/passenger, the eye just can't perceive more detail.
The smallest full 1080p screen I have on hand (1920*1080) is on a small notebook-size laptop and it's a 13.5" screen designed to be viewed from close up (18" or so).
This guide is quite interesting: https://www.rtings.com/tv/reviews/by...e-relationship
Extrapolating that guide, assuming a viewing distance of between 2 and 3 feet, a 7" screen is only worth being 480p, for 720p you'd need a 10" one. And for full 1080p at least 15" or 16".
I'm sure Stephen can tell us the size and resolution of a Tesla centre screen shortly...…..
(Though I just looked it up and it's a 17" screen with roughly 1080p resolution, though newer ones are about 20% higher resolution, so in the right range)
