My '06 came with Bluetooth and BMWAssist - I've ordered the phone tray for my E815 - the dealer also ordered an antennae that fits in the bumper to go with it (7/5 install date) - I asked if this was needed and she said it was on the list for the phone cradle install - I'll know more Thursday, but maybe that's why you are losing signal????
