Hello I was searching to know why my truck I just started chiming yesterday. My daughter and I went to the store and I lat her drive and I set in the passenger seat. When we were in motion the chiming would start but nothing show on the screen.. So now I'm reading that others are experiencing the same thing. Someone mentioned in the forum to check seatbeats., doors etc..So now I'm remembering what happened while I was sitting in the passenger seat. I kelp fastening the seat belt in the wrong clip. I was putting it in the middle one. under the arm rest!!!! Hopefully that helps ..
