I have a Nexus 4, which is running KitKat 4.4.2
I got new car last week 'Vauxhall Astra Excite' which has Bluetooth as standard.
I can pair the Nexus 4 no problem with the car, but neither dial nor answer works from the controls on the steering wheel or the buttons on the Infotainment system.
Tried it with my hubby's IPhone 5 which works no problems, and it also works with my daughters Samsung S3 mini which is running JellyBean.
Googled the problem, and it seems that KitKat has some serious Bluetooth problems.
Is there anyone else here having problems with KitKat BlueTooth?
