13/20: correct ...

Here are the contents of the box GPS: a cigar-plug 1.5 m, USB cord 0.45 m, a mounting bracket for windshield with suction cup, a cord-antenna and a Quick Start manual. However, there is no protective cover, apart from that, there is nothing to order more !!
After 15 days of use, I would say:
- Capture super fast geolocation satellites,
- Guided by a very synthetic voice, drawling the word endings that gives oriental accents ... it is exotic !!
- The time and route guidance is ok on motorways and main roads, but once we attack the secondary roads is + random: for example, despite an update of the card upon purchase, the new fast lane of our sector (10 months) is not taken into account in the well qu'existante route on the map. Similarly, the route to our home through our town of 9,000 inhabitants is calculated by taking the most important ways and not more direct even if it is faster.
Usually and for my business trips, I use the free app on my smartphone WASE which is far better than all those dedicated GPS (Garmin and others), except the capture of satellites that can take 10 minutes with my smartphone, then it's almost immediate with Garmin. We are equipped with the GPS especially to have a guiding tool when I'm not in the car with the smartphone. If you have a smartphone, use the app WASE cord + cigar lighter (because that pump battery) and you do not need other GPS.
