Here we go again. A decade ago, luxury cars like Lexus and Cadillac which uses OnStar really screwed up. When the wireless 2G signal was turned off, they and customers lost their navigation and emergency services. You would think OnStar, carmakers and the wireless industry would have learned their lesson and never let this happen again to them and their customers. However, it looks like they did not.
Back then, Lexus used the OnStar system and branded their version of the service Lexus Link. Today, I am told Lexus still uses OnStar for their Enform navigation service.
