I have a 2014 Cadenza SXL fully loaded. When I start a phone call before turning on my car, the car refuses to transfer the call to the Bluetooth. It mutes all sound from the entertainment center and even prevents me from selecting AM/FM, Media, or Sat. It displays the person I am calling name and even the length of the current call. I took the car to the dealership where I was eventually told, "The Cadenza doesn't support call handoff". I thought it was a joke, but they were serious. My wife bought a 2014 Optima fully loaded the day before I bought my Cadenza. Call handoff works fine in her car and she paid $10,000 less for her car. I was told there is no firmware update either. I am putting this on every website I can find so that potential consumers will know about this shortcoming. Apparently dealerships either don't know about this or are conveniently forgetting to tell the potential customer. I love my Cadenza, but this is unforgivable! I had perfect call handoff in my previous vehicle, a 2013 Hyundai Santa Fe Sport Turbo.
