Thinking of a new gadget...

To further elaborate, please take a look at this picture below. The smaller display module is the aforementioned 0.92" 128x32 graphical OLED, the larger one is the smallest transreflective COG (ultra-thin) LCD I found. The LCD would definitely have to be bar mounted, competing for space and attention with GPSes, phones etc. The OLED might be squeezed in above the Honda logo, but the housing would have to be significantly wider (hence, a bit out of proportions and with less flowing outlines). The caliper is to illustrate the required width of the housing for this graphical OLED.

+1: Sentimentally, the CB is a retro machine - I'd be very careful to add anything overly modern-looking to it

Csory, how does the micro drive the led driver ic, ascii or something that resembles alphabetic and numeric input with a location?
Didn't feel like looking up the datasheet on the driver.

The [url=https://datasheets.maximintegrated.com/en/ds/MAX7219-MAX7221.pdf]driver IC is connected to the micro via I2C bus. It can be set up either as a decoder (basically BCD), or pass-through. I use it as pass-through so that it can display anything non-numeric too. Commands are passed to it in the form of "chip x, digit y, value z" - which will turn on one or more segments of a digit y of the LED chip x. (Value z is a binary mask for the 7 segments and the decimal point of that digit). There are a few more commands for adjusting brightness, testing segments, setting decoding width etc...
