The NAC Wave 3 uses P4CNS maps and the Wave 4 P6CNS maps. So, yes, that's an NAC Wave 4 system.

All the information is in https://sites.google.com/view/nac-rcc/system/aio/wave-1

Double-click the "Version" to also show the removed or unreleased to the public version.

The car can read any FAT32-formatted USB flash drive of any size. The filesystem itself can support up to 2TB.

I've a FAT32-formatted 128 GB flash drive, and I use it without problems, even for firmware and map updates.

The 32 GB "limit" is only in the format utility used in Windows (latest versions of Windows 11 removed this limitation), but it can read and write to FAT32 partitions greater than that. The "Peugeot Update" uses the default Windows utility to format partitions up to 32 GB, but uses a 3rd party "fat32format.exe" in the "bin" directory, for larger partitions. But to do that you usually need Administrator permissions (and to disable/configure "Controlled Folder Access").

Both files, 16.0.0-r0 and 17.0.0-r0, were updated in the last 2 days but have the exact same size as before.

It is just a guess, but I think this is related to the fact that NAC_EUR_WAVE3 systems could be upgraded again to NAC_EUR_WAVE4. But now most of these systems are old enough that almost nobody has a valid TomTom subscription (or WiFi/tethering configured), so the system can't connect to the Stellantis servers and report that the user has done the update. So "X Update" software or "MyX" apps (that use the Majestic API) cannot offer the right updates for those systems. They are probably getting a lot of complaints from users that finally could update their old NAC_EUR_WAVE3 systems, but now they're left without any map - it was old, but it was working.

This back and forth with versions and "X Update"/"MyX" is nothing new. They just don't know what they're doing.

It isn't mislabeled. In SWL/002*/MediaHeader/MediaVersion.ini:

MediaVersion=002315011708350505
; Up to 32 characters
MediaCreationDate=20240219144826

It might be possible now, as every NAC_EUR_WAVE3 is now identified as a NAC_EUR_WAVE4.

So just install the latest firmware version for the NAC Wave 4, 44.07.33.32_NAC-r0, but you can't use the DS/Citroën/Peugeot/Opel Update software

They really f*cked up, all NAC*WAVE3 systems are now identified as NAC_EUR_WAVE4, including the NAC_CN_WAVE3, used in China....

It should be 2D075039002970142579

See Here's how to find out the RCC Serial Number (UIN) for the License Key

There aren't any map licenses. The license is tied to a particular UIN (head unit serial number) and to the MediaVersion/UpdateID of the firmware update.

"license_xxxxxxxxxxxxxxxxxxxxx_yyyyyyyyyyyyyyyyyy.key":

xxx...x is the UIN (serial number), 20-digit hex number;

yyy...y is the MediaVersion/UpdateID, 18-digit number.

And you can easily see that your license filename has an UpdateID of 001... (probably 001315031666020829 of the latest NAC Wave 2 firmware 21.08.90.52_NAC-r0) and NOT 002... (002315011730118165 of the 28.0.0-r0 European map).

But that's not a WHD touchscreen with the temperature displayed on both the left and right sides (those 320x720 areas). That's what people usually refer to as full-screen CarPlay/Android Auto.

The other 2 screens (SD and HD) only have a small bar on top and bottom.

The UpdateID 001315031613548831 (that you used in the previous URL to download the license) is for firmware version 21.08.87.32_NAC-r1. That license obviously doesn't work with the latest firmware version for the NAC Wave 2, 21.08.90.52_NAC-r0 (UpdateID 001315031666020829).

But if you use the Toolbox to prepare the USB flash drive, everything should be fine.

The UpdateID you posted (3C0023...) is invalid, but any UpdateID that starts with "0023" is a map update and those doesn't have any license to download.

With this information (1st post)

HMI version: rcc2019.82.19.16.2.1.00
iMX version: x0401065_190620_19.1E027.2
V850 Version: RCC19_19.1S18.5

It's clearly a RCC Wave 3 (RCC_EU_W3_ECO) with the 1st 084 system version installed (UpdateID 005315191561110251).

It doesn't make any difference - any software that uses the Majestic API, using that VIN will download the updates for the NAC Wave 4 system.

It isn't the first time the information stored in the Peugeot/Stellantis servers is wrong.

As I wrote, he needs the original VIN from where that RCC came from (probably impossible to know), or the UIN that he could find in the head unit's label. Because it's a RCC system, without using a diagnostic software, it's is impossible to know the UIN. In a NAC system, you could use the "export config" option and find the UIN in the created files. Or find it in the spylogs. No sush options on a RCC system.

By the way, the UIN from that NAC Wave 4 was validated in January 2020:

[
  {
    "uin": "0D01152109D4F220799A",
    "creationDate": "2020/01/19 05:15:12",
    "updateDate": "2020/01/20 16:15:06",
    "type": "create",
    "status": {
      "code": "VAL",
      "label": "Request validated"
    }
  }
]

murpi89 To download the correct license, you need either the VIN of the car from where that head unit came, or the labels in that head unit:

Here's how to find out the RCC Serial Number (UIN) for the License Key

I changed my RCC A1 for an RCC A2, however, I didn't know the VIN number of the donor, I don't have an Arduino or Diagbox, so I couldn't know what the serial number of the RCC A2 was, to generate the license key for that I could update my RCC A2.

When preparing the update pendrive with my car's VIN, for the RCC A1 (using Citroen Update), I noticed that part of the UIN number that appears is on the RCC label. The only part that is not on the label are the first three characters (2D0). Look at the…

murpi89 You have a Bosch RCC Wave 3 head unit and you're trying to install a Continental NAC Wave 4 firmware...

Yesterday was released another RCC Wave 3 firmware, 6_0431_23.2I41.1, maybe it can help with your problem.

If you install this new firmware, please post here the HMI. iMX and V850 versions.

That is already the latest firmware version for the RCC Wave 3.

And in RCC systems, you cannot reinstall the same version, only upgrade.

It is also impossible to install any map update for the NAC Wave 3, they all have, you guessed it, expired signing certificates. Right now, you could only install:

It seems the 44.07.33.32_NAC-r0 firmware version is available again in PUB status.
It should be possible to upgrade using the Peugeot Update software or with an online installation (without the license key on the USB flash drive):

{
  "updateType": "ovip-int-firmware-version",
  "updateVersion": "44.07.33.32_NAC-r0",
  "updateProvider": "CONTINENTAL",
  "updateId": "001315031692686757",
  "updateDate": "2025/01/28 12:39:24",
  "fileName": "PSA_ovip-int-firmware-version_44-07-33-32_NAC-r0_NAC_EUR_WAVE4.tar",
  "updateStatus": {
    "code": "PUB",
    "label": "Publié"
  }
}

The .tar update file is exactly the same, there's no need to download it again if you already have an older version (it hasn't had any problem in the first place anyway...).

The previous 44.07.05.22_NAC-r0 version is still in AVP status and probably died right here...

No, you can't install a Chinese firmware for the NAC CN Wave 4 on a NAC EUR Wave 4 hardware.

Also, the Chinese versions use a cartography/map sold by AutoNavi that isn't compatible with the EURopean versions (P6CNS format) and the TomTom doesn't have a cartography for the Chinese territory (although they have the name "map-cm" reserved and the respective 00231565... UpdateID/MediaVersion).
