Has anyone had a problem with their Navigation screen freezing up. Our screen says Initializing and stays in that mode until your turn the car off and open drivers door. IN addition, there are other times where you can put int he destination address and start driving, but the screen never changes so it looks like you have never moved. I have had at dealership a couple of times and they say they cannot get it to act up, YET I have video taped it on my phone as proof that it acts up. In addition playing music from a a cell phone through blue tooth also is static. I personally believe that since the Navi/Radio are all on unit that is in that assembly.
