I am attempting to wire a Parrot Bluetooth adapter into my 328i. It's easy to do if you have the plain Jane stereo using an available ISO cable adapter but the same is not available for the more complex NAVI equipped audio controller. So I need to splice into the system manually. Among other issues, I cannot locate a MUTE wire in the audio controller harness (or anywhere else). Can someone tell me if there is one available somewhere in the front ?

Another issue is that the Parrot relay control box wants to deal with speaker level audio (already amplified) so I would need to work with the wiring coming off the amplifier in the boot which I want to avoid. The Parrot unit *does* have a pair of line level audio outputs. Is there a simple way to integrate them into the line level wires coming out of the NAVI audio controller ?

Any info/guidance appreciated.

Thanks.
