So before I drove off from the dealership in Chicago, the young Tech girl spent about an hour going over all the buttons, bells and whistles. All was good and she ended with On Star. She went over everything, even had a trial call to show how it works. Then I asked her what plan she recommended? I was figuring the most expensive but was shocked when she said, "None of them. Biggest waste of money you could spend!". Wow, I thought. I said why? She explained there are problems with the hotspot being too slow and said the hotspot on your phone (which you are already paying for is faster). Also said the cars navigation and your phone's is more advanced than On Star's. The convincer was when she said that even though you are not paying for the accident/stranded service, that by law they have to answer and send help to ANY distress/stranded call. Oh my. Any of you using it?
