Wow, a car stereo with a large display like that is surprisingly advanced for 1985! I wonder if this is really a CRT, or a multi-segment display made to look like one

It’s a segmented display. Color display on consumer computers was to expensive at the time. because of the limited memory you could either have high resolution or few colors and low resolution, and high resolution was required if you need text.
My guess is that all displays have fixed segments and warning lights that can only be turned on or of.
