Is it just mine or is the gps not accurate with streets and towns. I understand they need updated time to time but, I have streets in town that have been here since 1922. Same with towns. We have a town called Barnard, small town fourty miles from where we live. The gps said you have reached your destination in the middle of the highway. The town was 15 miles away. Who did cadillac use as a vendor to program these disks.? And will a undated disk fix this and where to get them.also you can't put in a destination while moving. Is there away to bypass that feature.
