Using TomTom Start 60 always get the message "Route erased"
While driving with navigation from the TomTom Start 60, I always get the message "Route erased". Then I have to set the route back ... and again after a few minutes. That keeps repeating itself. It is annoying and also dangerous if you keep having to re-enter the route while driving and you can't stand aside every minute to re-enter the route.
What is the problem?
