Why does not the phonebook download to my car

My Lumia 1520 does not download the phonebook to my car (Huyndai I40) when connected via bluetooth (pairing is OK). Why?
My prevous phoen 920 worked OK with this. Any special setting needed or any other info from any expert on this?
Phone running W8.1 OS-version 8.10.12397.895
Anything to do with NFC?
Appreciat any comment.

Not sure on the why, but its the same in my 2012 Chevy Malibu. Pretty annoying as you have to actually say "voice" in order for it to launch cortana on my phone, wait for it. Then say a name for it to voice dial. Instead of just saying dial and give the name.
