A star is available for quick delivery. Actually you should ennoble the unit with "zero stars because the specification and also downloadable on the internet instructions and the enclosed 200-page pamphlet in no way corresponds to the device. Essential things like putting together described a route of several Anfahrpunkten, the indication of danger zones (sometimes quite useful), etc. Although broadly described ... that there's anything at all on the device. The most important for me settings for the display are in the operating instructions only in a so-called "advanced mode" is only possible but, as you can almost guess, not being selected. This peripheral and the product significantly deteriorating software changes seem to be the supplier probably escaped completely although the software used to compile three years ago, and certainly since then been on the market. Since you can only amazed the quality of the supplier. Several calls to the technical service hotline also brought no success and were partially answered only with terse emails. Here to talk about buyer deception is certainly not entirely be dismissed out of hand since the EC law makes clear provisions regarding instructions for use and marketing of technical devices. The display in the default mode is very dull and almost unrecognizable streets off the route in daylight. Night mode, however, is okay I'm very disappointed with the device and also of the supplier, will thus return it and hope that it works at least smoothly.
