Old Timer Needs Help Updating ( But only a bit)

[Firewatcher]

Hello All,
I currently have a 1970s Radio/Cassette that is like it's owner - a bit past it. I still want to use the cassettes I have, so have acquired a Blaupunkt Car 300 Unit (@1990's) which looks OK, and I hope to install. My problem is that the unit has no integral display but does have Data output pins marked SDA-1 Bus Display, SCL-1 Bus Display and MRQ-1 Bus Display.
My Motor is also Vintage and doesn't have a driver info display, and although I can probably manage without it - It would make it easier if I could view the display info. Also easier to decode it, as at present I have to count the key presses and hope they register what I think they should.
I am OK with the other wiring, but is there a way of connecting the data output to a simple LCD display. Before anyone suggests it - I dont have a mobile phone, so it has to be lower tech.

Problem resolved - Found a scrap Astra that was fitted with that same unit. Salvaged the Display and original plugs and wired it up on the dining table. Found a code generator online and all works perfectly. Also picked up an outside air temp sensor, so have Time, Date, Temperature & Radio/Cassette status in my Vintage Motor.
