The Infotainment CAN wires are usually organe/brown (low) and orange/lilac (high). However, in some cases these wires are the Comfort CAN and not the Infotainment CAN. Audi radios seem to be able to use either of both, the RNS-E can only use the Infotainment CAN though.

I would try to use the existing orange/brown and orange/lilac wire and check if the RNS-E illumination turns on when you turn on the lights. In this case chances are good that you got the right CAN. In any case you will most likely need to code your unit for an A6 and find the speed wire.

depeneds on your car, The A6 C5, A4 B5 and likely the A3 8L don't have speed over CAN and need a seperate speed wire

and if it is confort,what can i do then?

Try to get the Infortainment CAN from the instrument cluster or use a CAN adapter.
