Please help! The radio in my wife's 2001 X5 4.4 keeps switching to "PHONE" every few minutes, stays in phone mode for a few minutes, then switches back again, and repeats the cycle over and over. She really can't use the radio due to this annoyance. The vehicle has the BMW phone in the console, but we don't use it. I have tried every button I can find to push while it is in phone mode, but it will not go back to "FM" (radio) until it has decided it is ready to. Anyone know how I can stop the radio from cutting out and going into phone mode every few minutes? Thanks!
