Kind of a silly question, but how do you switch between data sets? I mean, I have programmed 2 of the three, and can manipulate the sets, but whenever I shut the car off, and turn it on, the main display screen always reads ds:1 , which indicated to me that I am in dataset 1. When I am editing each data set it clearly states ds:1, ds:2 etc, when in edit mode. I simply want to tell the PMS to use the data set of my choosing. Shouldn't it display ds:2 or whichever set I choose on the main display screen?? Thanks!
