Today we’ll be performing a teardown and analysis of the Rivian “Autonomy eXperience Module”, or AXM. The AXM is a core part of the Rivian R1S and R1T vehicles, controlling driver assistance, media playback, infotainment display, and essentially all ADAS/infotainment tasks in the vehicle!

Now that we’re fresh into the start of 2026, I thought it would be interesting to take a look back at the state of automotive cybersecurity. To do this, I wanted to answer the question of: What is the state of automotive vulnerability reporting in 2026?

Another day, another teardown - and the first blog post of 2026! Today we’ll be looking at the BMW IDC23H infotainment unit, manufactured by Harman Becker.

The IDC23H is one of the newest infotainment units from BMW, as of January 2026. The design is based on the previous-generation MGU22/MGU22H, and is used in a wide variety of BMW models - this unit in particular was found in one of BMW’s newest X1 U11 SUVs.

For the past 2-or-so years, I’ve been hacking on my car’s infotainment unit - the BMW NBT EVO HU. I figured this would be the perfect opportunity to dive into a new topic: What does the boot process of a modern QNX-based infotainment unit look like?

Today’s teardown is of the BMW NBT EVO HU, an infotainment unit built by Harman Automotive - sound familiar?

When poking at binaries on a QNX-based system, you may run into an interesting ELF header: The so-called QNX_info section!
