[Loadstone] N82 Question

[Juan Haro]

I read the manual and I still have many questions.  

Using an N82, will I have to purchase an external GPS receiver?

What do I exactly download from the point share web site?  Does that give me the street info or POIs like restaurants or both?  Is it advisable to only get info for a small area or can I get info for my whole state or adjacent states?  

Any help is greatly appreciate it.

Juan
