Ive been lurking for a few days but I dont see a direct answer to this question and hoping that someone can help me out. I recently bought a pre-owned 2016 without nav. My problem is that my icon on the traffic map and the default weather location are on the other side of town and thats not exactly accurate. I cant for the life of me find where to change that, I did a data wipe but all that did was clear my presets. Any help or ideas would be appreciated.
