From your description of the area I think you may have a defective unit.
I agree, I think you may have a defective unit.
In North America, in a clearcut area where you have a clear view of the sky, you shouldn't have any problem. I have a eTrex Vista and only run into problems when I get in real thick tree cover. Even then, if I stand still for a while I usually can get a signal.
How long are you waiting for a signal?
