R8 with RNS-E and B&O Sound. How to add Parrot CK3100 car kit

[perleman]

Hello
I have an R8 with the incredible (!) RNS-E 2G head unit and B&O sound
I have bought a Parott CK3100 car kit off the bay of E for the princely sum of £40 and when it arrives will be installing it
How do I tap into the speaker line though for the telephone sound, as the ISO part of the Quadlock doesn't have any speaker connectors
Please tell me I don't have to run a speaker level cable to the B&O amp in the back and tap into it there?

Thanks

Done a bit more searching and think I can patch it in to the RNS-E's tel+, tel- and mute - have bought a Quadlock extension cable to hack into rather than cutting the car's loom. Only question is... will the RNS-E need coding that there is a non standard tel kit so it does the muting and routing of the phone audio?
