Change language RT3

This is the RT3 unit and was made by Magneti Marelli
The RT3 was available in a few different hardware versions, the later ones supporting MP3 playback. These units had an optical connection to the Display Screen.

Version of my current soft is 5.5D
Hi, do you still have the ROM with firmware 5.5d? Thanks

Hi everyone,
I need to change the system display language from German to English on my Citroën C4 Picasso (2007).

My unit details from the diagnostic menu:
Head Unit: RT3 CAN-bus
Soft-Version Steuerge: 6.63
Display Soft-Version: C30CE0C35

Could someone please share a link or point me toward a working ISO image for the RT3 CAN v6.63 software disc?
Thanks in advance for the help!
