They can be an adventure! They can be a real help if in new territory.

HERE there is a new (10 years old loop on the east side of Temple TX) before the latest update it had you cross the loop, make a right on a really old road, go to the Loop, make a right turn to get on the loop heading where a simple left turn at the intersection would have taken you.

Another time I had some time and told the little lady "Home" from a restaurant in Waco TX. It was on the shortest route option and I went down roads that had not been used for 30 years.

Usually it is better to keep the little dear on the fastest route.
Some times you may use local knowledge and put in a Via Point that will have it navigate on a perfectly good farm to market road.

Sometimes the little lady knows the best way from here to there. Far better route than what you have been using for 60 years.

The worst complaint is how "she" pronounces names. That was the advavtage of the novie 200 @ $200, then she only said turn in 500 feet & turn now.
