1: Manual - unclear
2: Software - Very poor, counterintuitive operation and controls, seems like it was designed for MS Windows 3.1, I mean really bad!
3: Read the fine print about how much it costs to download satellite images. Each zoom level of the same image, is a seperate image charge, so it can get pricy quick. The image quality isn't that great, this would be better suited mated to a notebook computer with a USB GPS.
Not worth the trouble to use like an ordinary GPS, stick with the better known brands.
Pros: Great "idea" to use aerial images with a GPS map
Cons: Not ready for prime time
