Hello all, I am french so sorry if my english is not perfect!

I have an Audi S8 from 08/1999 with RNS-C. I have replaced it by a RNS-D with TMC box.
I searched for many months for an used TMC box to keep radio, cd and navigation display in the instrument cluster.
I found on ebay a TMC box and I mounted it this week-end.
After recoding the RNS-D and the instrument cluster, navitagion display work fine but there is no Radio and CD display in the instrument cluster. Also I lost TV

Someone could help me?

Many thanks!!
