I bought the device (English - German) in order to communicate better and my English a little refresh. It should be noted that only the preset phrases are used. The translations are therefore, if one sets the translation pretends not always perfect, sometimes even wrong. Customer service is not quite as you imagine it. Questions about the device not been satisfactorily addressed by the seller, a proper description of the individual functions is not included with the device. The device has indicated that you can download a Download Program for the navigation system at the manufacturer (specifying the download location) Unfortunately, this download on the website of itravl.net not find. Thereupon, I started a mail request, which was not answered me. Customer = null !!! You obviously want to sell only equipment. Conclusion: The machine can be a little help when you have a little concerned with, however, is not to be irritated by the advertising, because just talking and automatic translation of what is said does not work, you have to use the preset phrases here and can Play this loud ................
