Good choice. Since you have an F22, you likely have NBT or NBT Evo. The ENET cable is the only reliable way to pull the data for those units.
One tip for when the cable arrives: Ensure your Windows Firewall and Antivirus are temporarily disabled when you run the reader. They almost always block the network connection to the car's IP address.
Let us know how you get on!
When I connect to my OBD port using an Enet cable and run the FSC-Reader program it connects okay and discovers the VIN but gives the following error:
Ediabas not found! Only integrated EdiabasLib available.
--
Use EdiabasLib instead of original Ediabas, change settings in EdiabasLib\EdiabasLib.config.
--
I've looked at the config file but not sure what I need to change to make it work.

This is a common issue when you don't have the full BMW Standard Tools suite installed on your laptop. The tool is trying to use its internal driver (EdiabasLib) but it defaults to the wrong cable type (usually USB).
You need to manually tell the configuration file to use the ENET interface.
1. Go to the folder where you extracted the reader.
2. Open the folder named
EdiabasLib (or look in the root folder if it's there).3. Right-click on
EdiabasLib.config and choose Open with > Notepad.4. Look for the line that defines the Interface. It usually looks like
STD:OBD or STD:USB.5. Change that value to
ENET.It should look something like this:
XML:
<Configuration>
<!-- Other settings -->
<Interface>ENET</Interface>
<!-- Other settings -->
</Configuration>Save the file, close Notepad, and try running the reader again.
If that doesn't work immediately, ensure your Windows Network Adapter for the Ethernet connection is set to obtain an IP address automatically (DHCP), as the car will assign an IP to your laptop.

That message ("Ediabas not found! Only integrated EdiabasLib available") is actually normal if you do not have the full BMW Standard Tools (INPA/NCSExpert) installed. It just tells you that the program is using its own internal driver to talk to the car, which is exactly what we want it to do.
If the VIN is showing up, that means the connection is partially working!
However, if it stops there or fails to read the actual FSC file, try these steps:
- Firewall: This is the most common issue. Even if the VIN reads, the file transfer can be blocked. Completely disable Windows Defender/Firewall and any 3rd party antivirus for a few minutes while you try to read.
- Run as Administrator: Right-click the .exe and select "Run as Administrator". The tool needs elevated privileges to access the network ports correctly.
- Check the Config Syntax: Open that config file again. Make sure the
ENETsetting is not inside a comment block.
XML comments look like this:<!-- <Interface>ENET</Interface> -->.
If it has the<!--at the start, the program ignores it. It must look like this:
Code:<Configuration> <Interface>ENET</Interface> </Configuration>
If the VIN is populated in the box, you usually just need to click the "Read FSC" (or "Read 1B/DE") button to actually pull the file. Does clicking that button produce a specific error?
Turning off the firewall and running as administrator got a bit further. The read FSC button became active (not greyed out) but gave a read FSC error when clicked - see attached screeshot. In the config file snippet attached to my last post the ENET interface key is not commented out although there is a comment in the file where STD:OBD is specified.

Since you have an F22 M240i, there are two very important things to check, as this error usually indicates a mismatch between the tool settings and your car's head unit.
1. Wrong Read Button
The error often happens if you click the wrong button for your car type.
- Read 1B: This is strictly for older E-series cars (CIC). If you click this on your F22, it will fail.
- Read NBT (or Read DE): This is the button you must use for F-series cars. It reads the
0xDEfile instead of the0x1Bfile.
2. Map Compatibility (Critical)
Before you spend more time debugging the reader, please check your current map version in the car (Navigation -> Settings -> Position & Version -> Version Information).
- If your map version is Road Map EUROPE EVO:
The FSC Generator 1.91 tool cannot generate codes for EVO maps. This generator only works for MOVE, MOTION, PREMIUM, NEXT, and ROUTE maps. EVO units use a different security method; to update EVO maps, you typically need a "Feature Installer" раtсh (USB solution) or a purchased code, as the classic kеуgеn method does not work. - If your map version is Road Map EUROPE NEXT:
The tool will work. Ensure your ignition is fully ON (press Start button twice without foot on brake so the dashboard lights up fully) before clicking "Read NBT".

No, absolutely do not abandon the project! ROUTE maps are fully supported by the key generator.
The issue is simply a technical mismatch with the "One-Click" reader tool you are using.
Here is the explanation:
- NBT (Next) head units store the activation key in a file called 0xDE.
- EntryNav (Route) head units (which you have) store the activation key in a file called 0xDF.
Since you have the ENET cable, you can easily pull the correct file using the standard BMW tool called E-Sys. It is much more reliable than the simple reader.
Here is how to do it:
1. Download and install E-Sys (any recent version like 3.27 or 3.30 is fine, you don't need a launcher/token for this specific task).
2. Connect your ENET cable and launch E-Sys.
3. Click the Connect button (top row). Select your chassis (e.g., F020 for F22) and select "Connection via VIN".
4. Go to Expert Mode -> FSC Extended (on the left menu).
5. Fill in these fields exactly:
- Diagnostic Address: 0x63
- Application Number: 0xDF <-- This is the specific ID for Route maps
- Base Variant: HUENTRYNAV (or try HUNBT if that fails, but usually EntryNav)
- Upgrade Index: 0x01
7. Click Read.
8. Click Save and name the file something like
my_car.fsc.Once you have that
.fsc file:1. Open your FSC Generator.
2. Instead of clicking "Read", look for a button that says "Load File" or "Open".
3. Select the
my_car.fsc file you just saved.4. Select Map Type: Route.
5. Select your Region and Year.
6. Click Generate.
It takes a few more steps than the "one-click" solution, but it works 100% for Route maps.

You're welcome!
Just one final tip since you are using E-Sys for the first time:
When you are in the FSC Extended tab, be very careful to type 0xDF into the Application Number field. If you accidentally leave it as the default (or 0xDE), E-Sys will throw an error saying "Application not found" because your EntryNav unit doesn't have the NBT application.
Good luck, let us know if you get the code generated successfully!

Will do.
Tip: Connect the cable to the car and laptop and wait about 30-60 seconds before launching E-Sys.
Windows needs a moment to assign the fallback IP address (you will likely see a "Limited Connectivity" or yellow triangle icon in the taskbar—this is normal and required). If you launch E-Sys too quickly before the network interface is active, it might not find the VIN in the connection window.
Now that you told me that I have EntryNav (Route) I noticed in the FSC-Reader program that I have there is a option in the SWID drop down menu for EntryNav (DF). I selected this and I was able to read and save a FSC file. This appears to be a binary file with only a few readable characters showing the vehicle manufacture date. Does this file contain the FSC code ?

That is excellent news! You found the missing setting.
To answer your question: No, that file is not the code itself.
That binary file is the digital signature (specifically the 0xDF file) from your car's head unit. You cannot read the activation code inside it with a text editor. Instead, that file acts as the "Master Key" that allows the generator to calculate the specific code for your new map.
Here is the final step to get your code:
- Open your BMW CIC/NBT Key Generator software.
- Look for a button labeled "Load File", "Open FSC", or "Browse".
- Select the binary file you just saved from the reader.
- In the generator settings, select:
- Map Type: Route
- Region: Europe West (or whichever region your new map is)
- Maps: Select the specific year/version you are installing (e.g., 2024-1)
- Click Generate.
The box at the bottom will then spit out the 20-character alphanumeric code. That is the code you will type into the iDrive controller when you insert the USB stick with the new maps.

It is difficult to say for sure without seeing the specific error message text, but if your generator has "Route" listed in the Map Type dropdown, it is likely the correct version (usually v1.91 or newer).
However, this error is almost always caused by one of two things:
1. The File Size is Incorrect
Right-click the FSC file you saved and check "Properties".
The file size MUST be exactly 319 bytes (or sometimes 320 bytes).
- If it is 0 bytes, the read failed.
- If it is larger (e.g., 1KB+), the reader may have saved it as a text file containing hex code instead of a raw binary file.
2. The Generator Settings
Even if you load the file, you must ensure the "Code Index" or "App ID" matches the file.
- For Route maps, the App ID is 0xDF (223).
- Some generators default to 0xDE (NBT). Make sure to change this if there is an option, or simply ensure "Route" is selected in the map definition before you load the file.
Troubleshooting Step:
If the GUI keeps failing, look in the folder where your generator is. Is there a file called
Code:
fsc.exeIf so, you can try generating it manually via Command Prompt (CMD) to bураss any GUI bugs:
Code:
fsc.exe <filename.fsc> 0x00DF <RegionID> <MapCode>(You would need to look up the RegionID and MapCode for your specific map version in the swid_fsc.txt or Lookup.xml file included with the generator).
If you can post the exact error text, I can narrow it down further!
My last screenshot is the only error message I saw. My fsc file is 319 bytes in size.
I have attached a screenshot of my kеуgеn program window. The only options are CIC NBT or EVO. It won't allow selection of Map Type etc. presumably until the fsc file is open.
Unfortunately there is no fsc.exe contained in the zip file.

It looks like you are using a limited or older version of the generator that does not have the definitions for Route maps.
The error happens because your generator is likely hard-coded to expect:
- CIC (App ID 0x1B)
- NBT (App ID 0xDE)
Since your file is EntryNav/Route (App ID 0xDF), the generator tries to read it as NBT, sees the wrong internal ID, and throws an error.
You need to find the software version commonly known as "BMW FSC Generator 1.91" (by Jaeger).
When you open the correct version (1.91), it will look different:
1. It will have a "Map Type" dropdown that explicitly lists: Motion, Move, Premium, Next, Route, Evo.
2. You must select Route from that list.
3. Then, when you load your 319-byte
.fsc file, it will accept it because it knows to look for the 0xDF signature.Summary:
Your file is likely fine (319 bytes is perfect). Your software just doesn't speak "Route". Search for the 1.91 version, and it should work immediately.
