RNS-E installation

Dear all. I know there was a lot of RNSE installation discussion about that. I have got SEAT EXEO 2012 which based on Audi a4 B7. My car has had 3R0035186D Consert ll +EU .Recently I bought a RNS-E 3R0035192. I have it installed at seat service but no tel, no mfsw worked. I was told new bluetooth kit needed. I searched from ebay and bought newAudi Bluetooth Interface RNS-E A3 A4 A6 A8 R8 TT Freisprecheinrichtung FSE Set 8P1 862 335A.Today I installed it at service but it could not be coded by service. That is why I decided to search from forms and do it myself.
Is there anyone who has had any experiance about this issue please help me to solve that problem?
