The Nextion is cool but pricey and there is a lot of code to write.
It also does not come cased IIRC although you can buy/3d print enclosures.

A lot of people already have RCA component video capable head units.
E-Bay Reversing camera screens/mirrors are also very cheap.

Basic B&W video text/graphics can be generated by a $2 processor using serial data input.
The processor for that could even be incorporated onto the LiBCM main board with an RCA phono socket on board.

The we could just use a simplebutton/joystick serial encoder to send data to LIBCM or even a light pen LOL.. If LiBCM monitors the HLine then you could send simple serial commands via the OBDII port.

This all open source with docs/firmware. (I use it a lot)

Batsocks - TellyMate

TellyMate. A Serial to TV adapter. It outputs a PAL or NTSC composite video signal to create a 38 by 25 character display on a television.

A phone/bluetooth/wifi/4g app would be good but that needs a tx/rx hardware (module) at the LIBCM end for a start.

Comms would have to have some sort of basic security or at the next Insight fest someone wandering around could do some tweaking of all the LiBCM systems in range!

This was my Nextion stuff in a zip file.
I drove it with an OBDIIC&C (logging port) on the bench for testing.
Might be useful for you. I haven't looked at it for over a year.

Busy mainly.
With all this stuff Arduino/Nextion etc etc you have to put in a lot of work learning a new IDE/structure/language.
I just don't have the time at the moment due to my other PIC based projects/travel plans etc.

Nice progress @Natalya.

I think splash on/off can be combined/same.

I would say you def do not need to duplicate the OEM IMA display style.
Straight line horizontal or vertical bar graphs would be a lot easier.
