Thank you for your response mate.
In a post above,
@Tell mentioned about a way to check whether the files are original.
Now waiting for a reply from him, just to be on the safe side.
Yes it's an 8 signature... My memory
.
The modded firmware bungs code under the signature. No code below those signatures you know it's not been modded. Those 8 lines is the lock on the files indexed above from being hacked. It was a Vag design oversight that the unit was open to the exploit.

Whilst with a super computer you can work out the primary key that Vag uses don't reckon anyone has done that yet. But a weakness in the mib2 firmware was you could run code after the POI import method which is how all the modded firmware works. The green menu tool kits all use that plus the "AIO" software. It's still clever stuff since they have to compute all the hashes as well.
I have come across people that say it can be modded but you still have got to make that signature sla1 signature check to work. A tall order.
The same Vag primary key is used across all the mib2 products whether firmware and map files. The public key has been published so you can crank the check by hand which is what the unit does. If you have not got the primary key you can't manufacture the signature.
Was part of my education when looking at map updates. The navigation map file FeC was what I was really looking for as it turned out.
