Today, I turned on my P4P+ (integrated monitor) and the system automatically updated the firmware on the bird and controller. Very nice!!! BUT, I am not sure what would have happened had I not preflighted it in the house with WIFI. Quite possibly I would not have been able to fly. Always a good idea to preflight at home prior to flying but it looks to be a requirement with the 'plus'. BTW, I love this system though I have not flown much due to rainy days. (This is my 5th Phantom over the past three years.)
