nav question... what's the deal with setting a destination
 

by phone number? why would i do that? anyone here use that?

Very simple: you have the phone number of the business but not the address. :)

Or you can use it when some hot girl in a bar gives you her phone number.......bingo now you know where she lives. :D :D :D

if you have the # for the business, wouldn't you have the name????

It's just another form of searching. You can go by address, name, or phone.

What if you know the name but can't recall the correct spelling of the place? :)

Happened to me once, and the phone search found the place for me. :D
