Hi. Just joined.This is my first post on here. Hello everyone. No doubt owning a 407 i will have plenty of questions i will need answering. I have just bought my second 407. And i want to fit bluetooth in it,as factory. I have bought the radio with the TEL button on it, fitted and working. The control stalk with the tel symbol on it, fitted and working. I have fitted the small mic, plugged into the existing loom. I have bought the bluetooth control box . SIEMENS 9662258380. Does my loom already have the plug for this unit already fitted.Hope some one can help me out with this.Cheers Steve.
