Hi
For me and for now without problem:
1. Installation - ok
2. Setting - ok, but can't change the car, i get empty list.. It's also asked me for restore favorites and inserted my home address without problem.
3. Downloading of map - ok, but it's asked me like before, to reopen app and when i reopened it, the app crashed immediately. I waited 5-10 sec. and reopened it again - now it's opened without problem.
Today i will try to navigate and i will report later..
Thank you for your work!
