Yes, I have been having this issue for over 3 months, see my post Navigation System Stopped Working. The problem is infrequent, you never know when its going to happen, I recently went 41 days without any problem, and now its back again with a vengeance, every 2 or 3 days. One of the reason you do not hear much about it, is that a lot of people are using Apple Play or Android Auto. I recommend you notify Hyundai officially to include the manufacturer, currently they keep saying no one else has the problem, which means they are not working to fix the issue.This morning I noticed that on the map screen my location just stayed at the house and was not following my driving path, seems like maybe the GPS is not working and tracking vehicle movement.
Anyone else have this issue?
