Xperia Ray :: Bluetooth Car Kit CK-7W?

after reading horror stories and getting worried.. HOORAY the car kit works fine with voice dialling as well, using the built in recognition thats standard with the phone.My MW600 headset also works great, (although no track info on the reciever for some reason?) On the issue of the bluetooth car kit, when I activate the voice call with the Nokia Bluetooth control (a long press and audible tone), the screen on the phone doesn't switch on ie. I don't know what the phone is doing, ie the screen remains switched off ? Consequently, I don't know when to speak the contacts name, if the phone mis-dials I don't know ? I also get no audible confirmation of who's number its dialling (wich I used to get with n..ia)Any advice on whether I can address these issues in the phones settings ?
