NAV unit is not working

I have a 2008 Grand Cherokee Laredo with the Boston Accustics speakers, and back up camera. Over the past month the unit will turn on okay, but then as I drive, the screen becomes full of static and freezes up to the point where I cannot use UConnect, the back up camera, satellite/regular radio or the navigation. After a few minutes of this the unit will shut off then try to come on again. It is really strange. Does it sound like a software or hardware problem ? It has not had any updates to the NAV system. Help !
