As already mentioned in many reviews, it is mainly the poor workmanship of the plug, the games be played depending on the loose contact-whim with the GPS signal. Therefore, when you turn the device in the vehicle, it often happens that the navigation software must be stopped and then restarted, so that they can be synchronized with the GPS receiver. Runs all once, makes driving fun with this Navi. Even crossings with peculiar right of way in areas with many one-way streets were mastered superbly. Slightly irritating is the fact that instructions to turn are indicated relatively late on the voice control. What remains is the "endless" cable clutter in the car and the fact that the GPS receiver must be connected to the console and not on the device itself. In other words - the use of this bundle is only in the car possible, unless a car battery you strapped on your back.
