I saw a couple other people have had this problem, but I have not seen a solution. Today for about 40 minutes my 3 was showing its location incorrectly. It started just a little off and got worse as I drove, likely because it thought I was driving in a slightly different direction than I was. Here's a pic. I was actually travelling north on the road indicated, not off to the east as displayed: The real bummer was it thought I was on side roads, so it was limiting autosteer to 45 mph. Right before I got home about 40 minutes later it just fixed itself. Multiple scroll reboots didn't help. Has anyone figured out how to fix this? This was the first time this has happened. I am on 2018.21.9 still.
