Go to your bag (by pressing the X button) and select Key Items and select the Dowsing Machine. The dowsing machine will tell you where to go by pointing out a direction.
In Pokemon Black, the Dowsing Machine is automatic. When an item is in range, it will point in that direction.

First you open your bag and then press the key items part. Then you touch the dowsing machine then you got it to work!(you have to get the dream mist for fellet first) :).
