Anyone got Nokia 3230 working smoothly?

I have had many problems with that. I'm not sure are the problems caused by the car, or phone.

Ok, I got the devices paired, but when I make a call, it normally takes around one minute before phone automatically changes to hands-free. If I select "Telephone" from bmw menu, it always says "Please wait", nothing else. Sometimes when phone rings, I can hear my ringtone coming from speakers, but normally its just "beeeep... beeeeep". I cant access anything from the phone using bmw menu.

There is one exception to that, when I start the car and call immediately, I dont have to wait one minute before devices "are ready".

Also, I cant get the voice regocnition to work. I have that button on my steering wheel, but it does not say anything when pressed 3-5 seconds.. I dont know are these things related..
