The RNS-E doesn't have the same connectors as any Audi radio (Symphony, Chorus, ...) - so you need plug & play adapters to convert the connectors fitted to the car wiring to the connectors fitted to the RNS-E. Even the antenna connectors are different.Roch_Ultrasport said:Question?
Why would he need any adapters if he already has a B7?
Shouldn't he just be able to do a straight swap with the exisiting Audi Stereo.
That is to say the wiring harness in a B7 A4 should work with either the Audi installed Stereo or the RNS-E.
If you can order it as an option (probaly port installed) then everything you need ought to be in the car to install it.
I have a B6 A4 but I had a B7 I would look into it before buying things you may not need.
It's an OPTION (and NOT a port option) -they build the car differently on the production line if you order the RNS-E option.
