No there's no standard kit in the car.
I take lots of buisness calls in the car so decided a good old fashioned fixed kit was best.
I tried a bluetooth headset last year but I got frustrated with wearing it and charging it. It kept losing "pairing" with the Ericsson t610.
They do the fixed bluetooth kit but I didn't want to risk the pairing problem, I'd still have to put the phone somewhere in the car to charge anyway.
