INFO display gone wacky
 

Of course I can call the dealer and leave the truck, but maybe somebody can tell me which button to push to fix this. The INFO display comes on at Key On with total mileage displayed (OK so far). I start the truck and the display indicates no trailer connected, brake controller value set to 6. I can vary the brake proportion value normally. Display stays on trailer info unless I shift into R; then it switches to "Rear Park Aid (On) Off" and the rear camera works, but when I shift to D the camera goes off but the display remains the same until I switch the Key Off. INFO, SETUP and RESET buttons have no effect. Anybody see this before?
