Ok Google Bluetooth Hands-free issues



So I got a new car (2016 "facelift" Kia Ceed 4 Tech)... and whilst OK Google Hotword detection over bluetooth sort of works, the
state of the dialler appears quite broken... and I was hoping if anyone could help.

Nexus 5 running Marshmallow paired to the car with Phone & Media Audio selected.. Google Voice Typing settings set to record audio through headset if available.

1) With screen on, say "Ok Google" wait for phone to respond with the first and then second beeps (I guess the second beep is to
signify the phone is then listening over bluetooth)

2) Say "Call xxxxxx mobile/home" etc.

3) Phone responds and starts dialling. Call is answered and the car Infotainment screen gives a prompt to change to "hands free mode", requiring a manual button press..

Not exactly "hands free behaviour".. :) Not compared to when I pair my wife's Galaxy Note 4, do exactly the same steps and everything goes through seamlessly with
the car automatically going to bluetooth handsfree without requiring me to press the button on the infotainment screen.

Now if you look at the dialler screen on the Nexus 5 whilst the call is going through, you can see the dropdown to manually choose between "Headset" "Speakerphone" "Bluetooth"
and the "Bluetooth" one is indeed selected but clearly the phone and car aren't handshaking to tell the car to automatically default to handsfree. At this point, you can re-select the bluetooth
option but it doesn't do anything, and the car is still waiting for manual confirmation.

More weirdness is, if you start a voice call with OK Google but actually press the phone button to action the call, then it all works fine...

Both Marshmallow and the car are new, so I'm not hopeful that anyone has an answer but given the Note 4 works perfectly, I'm keeping my fingers crossed.. :)
