Mine has a totally different place to enable/disable the TPMS. (I don't remember exactly where. I think it is lower than the tire pressure menu selection though.)
When I originally purchased the unit I could adjust the pressure between 10-75, after an update the range is between 22-56. However, when I set it to 22 the driver's side rear still complains and wants 29. The other three are happy. If I set it to 23 then it wants 30??? I still have and want to use TPMS. I just want it set way lower. This issue is a known bug and they are working on it. I have a case number and will let update if/when it is fixed.
For now I downloaded the free TPMS disable and it works fine. (Note: this is actually a purchase, but it costs $0.00)
