ISA Map Update DIY with Fat32 USB Stick

[Fischvergiftung]

Good morning,

does anyone succsessfully updated the ISA-Map with the https://grenadier.mapupdate.info/ file?

I have downlad the MAP file > extract the .zip > copy the folder "dbupdate" on a fat32 usb stick > try to update the Car > always error messages > the files are damaged

I have try 2 different USB Sticks, always the same.
Maybe fat32 format over Mac OS ist the Problem...? Today i´ll try Windows with the same Workaround

Does anyone have a different solution?

Problem solved!

Update doesn´t work with Mac OS Fat32.
With Win Fat32 everything is fine.

I wonder if someone could crack this and put 100mph speed limits everywhere before updating.

OK insert USB after you are in Map update screen and it prompts you. What is this anyway? LOL

Hi. Once I plugged in the the usb stick on the port nothing happens. I go to Map Update and the QR code appears but nothing happens. Anyone knows why?

make sure you used a windows computer to format the usb. I had to first navigate to the map update menu, then insert the usb stick for it to recognize there is an update on the stick. Inserting the stick first at the Home Screen the system recognized there was a usb but did not start the update. I was fiddling around when I got it to work so ymmv

Does anyone still have the ISANA_24A download?
All that is currently available is the ISANA_25A download.
If you’re on ISANA_23A, like me, you apparently can’t go directly to ISANA_25.

Here you go

(free storage so expires after 7 days, apparently)

AI Overview
The INEOS Grenadier ISA (Intelligent Speed Assist) map update is
a crucial software patch released in 2025 to fix issues with the overspeed warning system, allowing owners to permanently silence the annoying audio alert, improve head unit functions, and fix various bugs, especially for models from late 2024 and early 2025 (Model Years 24.1 through 25.2). This update makes the system more user-friendly, often by enabling the helpful "Favorite" button for quick access to settings, rather than fundamentally changing the safety feature itself.
What the ISA Update Does:

• Fixes the Overspeed Warning: The primary goal was to let drivers silence the persistent speed warning sound, a major user complaint.
• Improves Head Unit: Addresses bugs with Bluetooth, Android Auto, media display, language settings, and tailgate opening.
• Enhances ADAS: Includes improvements to the Forward Collision Mitigation (FCM) sign recognition.
• Affects Different Models: Separate updates were needed for early 2024 models (24.1) and later 2024/2025 models (24.2+) due to different hardware.

The road sign database is definitely worth keeping up to date. But it takes a trip to the dealer for them to apply the firmware updates that allow you to disable the ADAS over speed warning and have the disable persist across driving sessions. Worth a trip to the dealer for its own sake, IMO, to get the firmware updates just for the less aggravating driver experience. AI is conflating updates in its summary, I think.

Big shout-out to everyone on this forum. I didn't know about the updates, nor how to do it. Went from 23a to 25a and the download/install actually worked! I am shocked. Whether it's an improvement is now the question.
Why didn't I get this at the recent 12K service???.
