for my 86 I use android head unit from aliexpress
Kapud Android 11 Car Radio 7' For Toyota Rav4/Hilux/Camry/Corolla/Terios/Aqua/Vish CarPlay AUTO 8Core DSP GPS WIFI 4G SWC BT

and it was plug and play, no need of any splicing or any advance wiring ( except for reverse camera trigger )
it comes with:
- carplay
- android auto
- google play
- 4g
- volume knob ( the main reason I chose this specific unit )
- front camera input ( you can make it run for 10s+ after reversing )
and it was cheap
but the quality its not the same level as known brands
built in microphone is the worst and I couldn't connect external microphone it refuse to recognize it specially in carplay app
so hands free call is not an option for now
this picture of my car after I install it 10 months ago
and another picture using carplay and also shows the brightness under the sun
