Normal one includes a product and the PC takes this right away. Here not. It takes great patience and time! There is nothing, absolutely nothing self-explanatory! The sheer size of this part is a disaster - fits around each foot .. So you firstonce starts tinkering ... Then you have to raussuchen the page to sign up - a lot of time and lots of patience! If you think it's done ... No - the polar part wants an update - but does not work, because you can activate this nowhere !!! I hope I get the part go again and advise everyone of them from !!!
