Summary: I am so disappointed with this tracker! I haven't gotten to use it even once, because it will NOT pick up signal, even in a flat field with no trees! My son tried it at the top of a mountain with no trees around, and it couldn't acquire the signal! It is an expensive piece of garbage!
Summary: I don't recommend this unit. The memory is NOT protected and all data will be lost if the 8mb battery dies..which is what happened to me..I was lucky to not be relying on this as a life support.
Summary: I don't have a clue how this item works - I just took it out of the box. What I can tell you is that it does NOT accept a cigarette lighter adapter, as one might conclude it would, given that Amazon and other dealers include a cigarette adapter as an accessory.
Summary: Being an owner of both the Garmin eTrex, and the Magellan 200, I find that: DOWNSIDE ---------------- 1) The Magellan is slow to lock on and frequently cannot get 3D accuracy with even 4 satellites. 2) The carrying case *blows chunks*.
