I heard that a regular Motorola v60 cellphone can be used in the new 5 series as a replacement for the BMWcellphone, which is $600 and essentially a v60 phone with a BMW logo on it. My dealer said that I cannot use my regular v60, b/c the BMW phone has a "chip" in it, and that my regular v60 without the "chip" will not work. Does anyone know if this is true?
