I have to defer to the ones that have navigation screens in the dash. I have never had one.
My feeling is that a nav system would be a distraction if only the driver is available to operate it. Even a navagator in the passenger seet can be a distraction.
I am interested in what others have to say about it.
If one can talk back to the system rather than punch buttons & screen it may be OK.
For the price of the nav systems one can get a good laptop and GPS roadmap program that will do 100 times as much and seems like a better option to me.
What I am talking about "voice overs" is the way they have "music" with narrations that make it hard to understand what they are saying.
Is it possible that the younger generation's brains are unable to stay awake without constant musical background? (incoming)
Best regards, Happy Jack
