Thanks. I know about that option. In the past, some owners have replaced 6 button front panels with Euro style 8 button panels, and coded their cars. I will check them, when coding cic.
But I'm confused a bit. Front panel is connected directly to cic, and both two don't use k-can to communicate. So, why front panel doesn't work with my car. Maybe frm recognized its a used cic and locked some features. Because navigation, sat radio and all stored stations worked at the first power on. But I have seen they were all gone after a short coffee break.
