The navigation screen has delaminated and no longer works. You can see where there are layers of screen that are discolored and has a matte finish underneath and the entire screen is erratic and works only 10% of the time. I cannot answer calls through the car any longer and I have to try to navigate long trips from my phone as this function of the car is down. It’s a serious problem and puts me and others on the road at risk every time I have to use the car as I travel by myself and I struggle to navigate the roads without this system. The car has a mere 70,000 miles on it and has been well cared for. I bought the car new and this issue is serious. There were no warning signs other than it erratically works less and less. I have researched the issue and see there are so many with this same issue that I wanted to add to the list. I cannot find a second hand part as the demand is too high. The car is available for inspection and I haven’t had it to the dealer for this issue. It has been inspected by an auto repair shop and agrees the component needs to come out and be replaced. Please help!
