Have a couple of these Avic's and themost reliable is my OLD N1. But I have a "Route unable to calculate" anytime I map out a destination from either my address book, or a new address. The only time I get it to work, is if I am within 50-75 miles of my destination.. and not sure thats a coincidence or not. I have reset the unit with the rest button and a power off. Still doesn;t work. This is the only function that fails and of course the most important one. Any one had this problem..thanks again
