The card is used by me with the Garmin 810 and the 810 was purchased especially for the routing function. The Navi is used with the card on the mountain. After a few day trips, I must say that hiking trails are mostly not recorded, but probably forestry paths. The routing control is slow when you type just right on the navigation target. For example, I gave my home address, and I had only 4 KM just go out and the Navi constantly reported "Please turn over". Official cycling tours, which are included in the standard wheel / hiking maps are not suggested, but instead streets. Even a smaller site did not recognize the card. Uncharted terrain of me I would never dare with this card, as you'd probably hopelessly lost.
Now I have the card or try with planned tours on the PC.
For the price this is simply unacceptable. The presentation of the runtastic Mountainbike Pro cards i.Zshg. with the Iphone is also far superior.
