This is the great difference with respect to the other systems, Navion system superimposes the signs on the road: the arrow to turn right at the next street is at the same intersection. Come on, you see it in having to take the eyes off the road. Indications of the system adapt to the speed of the car (seems obvious, but there are still many embedded browsers that are very slow when it comes to processing information).
Another important advantage is that you don't have a reflective surface on the windshield to be able to project information (identical to other models of GPS, such as points of interest or fixed radars). The need to treat the windshield and include a foil reflective (an expensive operation) is making on middle and low range models will opt for a small screen to project information.
WayRay Navion is a connected GPS that works only with a mobile connection (via its own connection to the internet or via a mobile Bluetooth). It consists of two elements, projector-GPS Navion, and Element module that reads the information the car (speed, for example) via the OBD port of the same.
The Navion is exclusively controlled by voice and gestures, and how it works via the mobile phone also allows you to answer calls, or use other features. While the Element, on the other hand, sends a range of data to a dedicated mobile where in later App you will be able to analyze your driving behaviour (speed, time between each stop, distance, etc).
For some time this part much has changed the security of our environment. A few years ago our parents were calm when we said them that we went for a ride and we would return in a while, becoming at times, but luckily we always returned home, with some bruising than other, but nothing that could not cure a little mercromina.
But to be part time, which have now ceased to be children to become parents, know of the insecurity that surrounds us. It is no longer the same thing a few years ago. And fruit that, occasionally, overprotection towards our children manufacturers are launching devices to be controlled at all times to the little ones.
