no problems fitting parrot to e60, would recomend to wait 20 mins till CAN shuts down to unplug radio, make sure to get the lead sot-976fb itll make it easier than just a normal 976, run your ignition live down to 12v for cigarette lighter is easiest, dont connect a mute wire. when you fit the parrot your i phone will work through the parrot usb anyway if you cant get it working through the cars usb, drop the glovebox its much eaiser to fit all the extra wiring back there! any more questions just ask ! ive fitted loads of these in e60s
