I've recently purchased a 2004 X% 3.0D Sport. I've managed to connect my Nokia 6280 to the Bluetooth but as soon as i answer or make a call i can neither talk or hear the recipient. When i look on the phone it has a picture of earphones next to the BMW35751 as opposed to the speaker which was shown next to my previous bluetooth kit as if the phone recognises the BMW bluetooth as a headset. Anyone help?

I'm also just about to change my phone for a new Nokia, can anyone advise best choice?
