Im preparing for the trip to west africa, and considering which GPS to buy.
So I got a few questions about that.
first of all, do I really need gps with maping data? If so, which is the best value to price unit?
What other things are important when looking for such a gps unit?
I was looking at some products and two of them interested me mostly. these are: Garmin e-trex (yellow) and e-trex legend. What do you think about that units? are they good choice for such a trip?
