Very delayed Navigation system

I just purchased a new 2014 Prius v (15 miles only) and one week to the day since my purchase my navigation screen went black. When I turn on the car, the Toyota symbol comes on, but it stays black after that, the "caution" message for the map doesn't appear. About 3-5 minutes later, the map will appear, but not fully loaded, some of the buttons on the map do not load but then eventually will in time. I try to change the screen by pressing on the radio button, but it will not display the stations and about two minutes later you hear a delayed beep from pressing the radio button. I try pressing other buttons (setup, destination, etc) but it won't change until minutes later and then it stays on that screen. I put the car in reverse and the camera won't even appear. I have turned the car on and off to see if that will help, but it doesn't. Has anybody experienced this problem? I will be taking the car in to the service department at the dealership on Monday, but I was hoping somebody here had a quick solution they have used with this problem. Thanks for taking the time to read this and any input you may have!
