I am in Germany on (sort of) regular bases. I always used TomTom maps wherever I have been (Bavaria, Rheinland-Pfalz, Hessen, ...)
I have good experience with TomTom maps and they never crashed.
Better said: 9.6.13.267029 regularly crashed on highways, proposing a detour caused by (to expected) traffic circumstances. With the very same maps, 9.6.13.405512 ran flawlessly, even proposing detours!! Never had a crash since.
And the most important, I never got lost.
