I'm confused by your comment because most people have Sentry Mode available to them (I have a HW 2.0 X). The USBs and 12v plugs turn on when you have Sentry Mode=ON. Easy to verify by plugging your phone into the 2nd row, as an example, while sitting in the back seat and use your phone to toggle Sentry Mode ON and OFF. Again, I used Sentry Mode recently on a 8K roadtrip to keep my 12v fridge on at night while not in the X.
