So just a quick update on turn-by-turn navigation - it will never work for the AU/NZ Genesis models of our generation.
I pulled apart the map binary for the US and compared it to the AU one and they're completely different. The US one contains code that sends the turn-by-turn information over CAN to the HUD. The AU map binary does not. That's basically it. Even though our HUD can display the turn-by-turn info (by kicking it into service mode with GDS), it never receives anything from the maps program to display turns. And it's basically impossible (very very very difficult) to patch it in without trying to break both the program (patching in stuff is hard) and whatever verification checks they do.
Same with
Apple Carplay /
Android Auto. I think Suburbazine was testing the AA/AC firmware from the newer (2018+) model but couldn't get any sound to work. That same software wouldn't even boot on my AU model. I think something went wrong when they brought the car here as the code is littered with comments like `// For AU model, need to disable boot` with code missing or removed to get it to run here. No idea why.
Shame. Took it for a service at the Hyundai Stealership as they said they were going to update the headunit as well but never did. Apparently they don't know how
