If I am in the car with my phone only connected via Bluetooth, I cannot find how to answer an incoming call. No icon displays on the infotainment system and there in no answer button on the steering wheel, only a hangup button. The manual doesn't show how (at least I couldn't find it). Anyone know? I am using an Apple iPhone. If the phone is in my pocket and I am driving I can't get it out in time to answer it.
