Thanks dave,
Yes everything works perfect, phone, Bluetooth, sat nav (badly needs an update)Bluetooth audio ,radio and voice controls. Was on a 3 hour round trip yesterday and only when I turn on the ignition and the hu powers up does the call trigger and mute the infotainment. When I had the boot open looking for the combox the radio came on by itself after 10mims or so which then triggered the call also. If I could stop or code out the call from muting the audio I could definitely live with that. I have bimmercode and bimmerlink via Bluetooth obd2.
