The Harley-Davidson Infotainment Control Unit (IFCU) digital dash system was first introduced on 2023.5 touring models, and if you’ve been following my content, you know how frustrating the original firmware update process was. It required two memory drives and a complex procedure, making it feel outdated—especially for a system that connects to Wi-Fi.

Well, Harley has finally made a big improvement with their latest 2025 software update. Now, you can update your IFCU over Wi-Fi, eliminating the old multi-drive process! And the best part? This update also applies to 2023.5 and 2024 models with the IFCU.

But this isn’t just about Wi-Fi updates—this software update also introduces new features and fixes major bugs, so I highly recommend updating as soon as possible. You can find the full list of changes on the Harley-Davidson software download page.

Before we jump in, just know—this is an update to my original, in-depth and comprehensive Infotainment Control Unit (IFCU) tutorial video. If you haven’t seen that video yet, I highly recommend watching it first, so this all makes sense. That detailed video will teach you everything you need to know about operating the IFCU, to include the fastest and most efficient ways to use the system, hidden menus, functions and capabilities, navigation procedures, how to integrate Harley Ride Planner maps, and how to update software. My video is the most professional and detailed video on the IFCU in the world and we’ve been the go to resource for Harley-Davidson in dash infotainment systems for over 10 years now. We also have a complete Boom Box Infotainment System Tutorial Series Of Videos. That was the in dash system Harley used from 2014 to 2023 models. 

How to Update Your Harley-Davidson IFCU Software

1. Check Your Current Software Version

Before starting, go into your IFCU system settings and check your current software version. The update process will vary depending on what version you are running:

• If you're running version 2237D or higher, you don’t need to use two memory drives.
• On the Harley software download page, you’ll see two files:
  • One for Memory Drive 1
  • One for Memory Drive 2
• If your system is version 2237D or higher, you only need to download the second file onto a single memory drive.
• If you have an older version, you must first insert Memory Drive 1 with the first file, then proceed with Memory Drive 2.

2. Update Process & Time Commitment

Be prepared to set aside about two hours to complete the update:

• Downloading the compressed second update file alone took me over 45 minutes, even with a high-speed internet connection.
• Once you start the installation on your bike, expect an additional 45 minutes for completion.
• Pro tip: Keep your bike’s battery on a tender to prevent power loss during the update.

3. Installation Steps

1. Uncompress the file onto your memory stick.
2. You’ll see multiple update files—each one represents a different part of the update.
3. During the update, your bike will turn off and on multiple times.
4. Each time, you’ll be prompted to continue to the next step. Be patient—some pop-ups take time to appear.
5. Do not remove the memory stick until the entire update process is fully completed.
6. At the very end, you’ll see a final confirmation message for about 10 seconds—stay at your bike so you don’t miss it!
7. Once completed, remove your memory stick from the USB interface.

4. Post-Update Steps

• You may see some warning icons after the update—this is normal due to the system rebooting multiple times.
• To clear them, turn your bike off for 60 seconds, then turn it back on.
• After updating, you’ll now see a reminder under the software update menu to periodically connect to Wi-Fi for future updates.

Final Thoughts

Harley-Davidson has finally modernized the IFCU software update process, making it much more convenient. If you own a 2023.5, to present Harley-Davidson touring model with the IFCU, I strongly recommend installing this update as soon as possible to take advantage of the new features, bug fixes, and Wi-Fi updates.
