Hi

It turns out (according to other forums / installers) that

quote

You can not route the sound through aux-in because you cannot tell the radio to automatically switch to aux when a call comes. And there´s no mute in on the radio because the factory phone systems send that info via CAN-BUS. There isn´t even an ignition lead on the radio (that you could cut with a relay when a call comes in), since the radio gets the info of ignition on/off via CAN-BUS as well. Next thought would be to cut the speaker wires with relays, but on 10 speakers, that would be quite a drag. So I´d say: Time for a professional install (if you can find a real pro that won´t chop up your E90 badly)

can anyone confirm this ?
