Modern cars have MASSIVE digital displays, loads of computers systems monitoring every subsystem and internal diagnostics running to the OBDII ports.
Why the hell can’t we get diagnostic feeds on our console or infotainment center?
I’m not aware of any car manufacturers selling their own diagnostic ASICs, so it’s not an extra margin to squeeze afaik…
What gives? Any insight into this beyond the usual muh corporate profits conjecture?
As other mentioned cheap ODB2 readers, but some brands offer a lot of diagnostic data over the infotainment system, they just won’t display them to you - for BMW I use AAIdrive (is foss, github/AAIdrive) and it displays some of the data on the main screen without a physical ODB2 reader inserted.
(And ofc custom navigation, VLC, etc)
I am going to spend my holiday break looking into this, thank you very much!
