Mercedes Benz

Hi i drive a benz c240, 2004 model. i wanna know how to connect a phone to use the telephone feature in my car. i have no idea of how to connect my phone (samsung sgh-e715) to it. any ideas? is my phone compatible? or do i have to purchase any other special kind of phone? i noticed that there is a telephone jack(or a bigger on) inside the box under the arm-rest of my car. but i dont know how to use it. help me.

It will not work, there are only certain phones that are compatible, like a motorola v-60
