I still think that my service manager took me for a ride in his TH earlier in the year and it showed the current gear without going to ERS. ( I was seeing the gears in a different spot than where you see it with ERS) My head tech tried to give mine an update so it would show the current gear and he was reading from a book that showed it would do it, but it didn't do it. Last time I asked about it he just laughed like it is not going to happen. He may have checked with FCA and was told it will not update it now. Since I learned of seeing it in ERS I have done that, but of course you have to do it every time you start in forward motion, but at least it does give me an idea what is going on when going forward.
