Took to dealer . GPS was 3 miles in error. Dealer kept trying to down load upgrade . After 5 hrs. of waiting they gave up and pulled a fuse to prevent battery drain . Dealer said they would contact corp. for new radio replacement . Now it's worse than before. Driver assist is out, no GPS , No radio , Side mirrors shows constant arrow, A C is not working either . Called corporate and complained . Both said they would get back to me . Salesman told me ,' this is a wide spread problem and there is no fix '. I don't drive it a lot because I have a motor cycle and have less than 10,000 mile on it .
