Hello all. I've read all the threads I could find on this subject and thought I would add some information. I've had a Rail 9.7 for some time with the latest update and don't have EMTB+ as an assist option. The dealer hooked up the Bosch diagnostic tool and it's not there either. Strangely, I recently picked up a new Rail 5 for a backup and it has the EMTB+ mode as an option from the factory. Any ideas?
