Hi I have an iPhone 6 for work and my iPhone X and cannot use the X for navigation any more. The X is often confused as to what road I am on and constantly reroutes. I compared my route home on a highway and the 6 correctly showed my route home whereas the X said I was on a sidestreet 2 blocks west and kept on rerouting me via local streets. I have tried the figure 8 method to recalibrate the X compass. What else could be going on? I noticed the GPS was kinda getting things wrong when I first got it on release day. Now I think it's getting worse. I have screen grabs of both phones during my last trip and the X is comically off target by about 2 blocks.
