I recently bought a 2004 745i. I love the car, but the phone is frustrating. I wanted to change it to BT, but the dealer told me it cost $1000. Instead of getting BT I decided to just get a V60 phone from motorola. At the dealer they told me that they no longer sold them, so I got a v60 phone from Tracfone prepaid. The fone works well and fits perfectly into the cradle in the center unit of the car, but on the idrive display it just says Reading Data, and nothing happens. Can anyone help me?
