BMW recently revealed the BMW iX3 and i3 Sedan, some of their latest vehicles based on their new “Neue Klasse” platform/architecture. Peeking at photos of the new interior, I couldn’t help but notice: They seem to have a new infotainment system!

The latest cars have a system that includes four displays (three panoramic displays embedded into the dashboard and one tablet-style one in the center), something that’s brand new to the latest generation of vehicles!

This post is a deep dive into these new infotainment systems, attempting to answer:

• What the heck is their new infotainment system?

• Does it use new hardware?

• A new OS?

• Are there any teardown pics online? (spoiler alert: yes)

Off we go, deep dive time!

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!

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!

Today’s teardown is of the BMW NBT HU infotainment unit, built by Harman Automotive. This head unit was used between 2012 and 2019 across a wide array of models in BMW’s lineup, in everything from their sedans to SUVs.

The goal was simple: For the past year or so, I’ve been poking at my car’s head unit in my free time. This has now escalated to the point where I have two or three of the head units…

They use a 1mm-pitch edge connector for debugging and development access, and I didn’t want to solder wires directly to the pins in an irreversible way. As such, I created a breakout board!

The device I’m currently working with has over five hundred shared libraries, all spread out across random folders within the filesystem. Bleh!

This is a common issue I’ve run into when working with embedded systems. You want to import an arbitrary binary into Ghidra, but first you have to spend 10 minutes tracking down where all of it’s shared libraries are located! A major pain.

But have no fear, a one-liner is here! (every Linux graybeard’s favorite saying)

In the beginning of December, I published a new tool I wrote for analyzing ELF files! This tool is aimed at helping reverse engineers and tinkerers understand embedded filesystems quickly and easily, through ergonomic methods of displaying in-depth device and binary metadata.
