Thank you for your willingness to help, but I don't think that is what I mean. The problem concerns basic voice messages, e.g. "leave the highway in 100 meters". As I wrote on the highway only this one message appears 100 meters before the maneuver. It happened to me that I drove downhill because I had high speed.
I would like the first announcement to be made about 1 kilometer before the exit and then repetitious.
