Just wondering if anyone else has experienced similar issues with the navigation, where it has disc errors, does not recognize that the disc is in, and sometimes does not calculate a route. Has been to a dealer for service twice for this and have had the same result, Dealer claims to have updated software and replaced the drive, and works upon leaving the dealer, only to revert back the next day. Thanks for the input
