Driver was idle to install. Automat. Driver updates did not work, so ran manually. Have the map bekommne along with their peculiarities to run. Screen occasionally darkens extent that one can not see anything more (reproducible errors). Online Support useless by manufacturer. Will continue to expand this card and installing me a real map. W8.1. This is only nice that the card is completely silent ... would just be nice if they would work better.
The purchase and the purchase were good, my disappointment relates purely to the product.
