There is no detailed manual. Therefore one has to play around for weeks. Also features are so abbreviated that you do not know what it means. The displayed actual speed while hiking is often too low, sometimes only half as large as real. This is too long a time display to your destination and referred to a too late arrival at the destination. This current rate is updated every second, thus they excessively varies greatly and can not be used, however, to drive a car for walking. The average speeds vote against. The same also applies to the current vertical speed, only in this case it is even more striking. When uniform walking uphill the unit will alternate between positive and negative values. Better yet, one would only every few seconds issue a value. Also missing the display unit m / h, as it needs a hiker. The representation on the map is not optimal, you should be able to move the image. In a profile change the unit went crazy. Addendum: This last point has been fixed, the device was developed by Garmin exchanged for a new one. Otherwise it is a nice toy that you like entraining.
