Query: Ridiculously Disapointing!

I travel a lot in relatively tough conditions in a 4X4. Last week I went into Northern Arizona--I figured...what the heck I might as well get a GPS to help me as I will be 70+ miles from the nearest town. Not only did the unit fail to get more than 2 satellites --useless for point recognition--it asked me for the lat and long of where I was!!! What a joke--Magellan sucks! Isn't that what the GPS is supposed to do? tell you where you are and not the other way around? Going to Garmin.
