Just took delivery of my 4xE on Monday. Backup guides disappeared on Wednesday. Found a solution on another Jeep forum that just worked for me. Turn the Jeep off. Start in Park and Emergency Break On; wait 20 to 30 seconds, which is a good idea anyway to let the care get going, I played with the radio; then release break and shift transmission to Reverse. The guidelines were back. So, I will start with this delay always. I think it allows UConnect to completely boot and get going. Try it and let me know if this works for others. Not sure I am ready to be "an early adopter" of this new "computer on wheels"!
