I was able to get 19B today. Tried yesterday by leaving a message for the Service Advisor at the dealer I purchased the car. No callback or update. Called another dealer's Service Advisor. He started with saying all he could see were the two campaigns I still need to get done. I tried to get him to the software update page, but it wasn't going well. He then said he would check with his service tech. After a minute or so, he was back and found the page in TOPIx and pushed the update. He was genuinely interested in getting this right.
Also, only Touch Pro shows the version number.
