I was looking at the Helm Inc website. They publish factory service manuals Chevrolet . I noticed that there were 2 different infotainment manuals listed, The first one P/N 95333807B which I assume is for the gas engine Cruze and P/N 23172811A, which is labeled for the diesel. I have the first # with an A suffix. Does anyone have an infotainment system Manual for a diesel? Did I get the wrong one? I am wondering why there would be 2 different Manuals?
