POI without coordinates

Unfortunately you must load the coordinates. The GPS units use the coordinates to locate POIs, not the addresses. What you could do is use MapSource to locate the addresses and list make them favoriates and then load them to your 330.

(0,0) are valid coordinates! In fact, if you look on Google Earth, this part of the Atlantic is very popular with POI creators

Seriously, though what would you do with such list? If you're wanting to navigate to each POI, then as Marinerjoe points out, they need to have valid coordinates. If you just want a list of addresses for some other purposes, then, I suppose you could do such a thing.

GPS does not (nor care to) understand addresses, only coordinates. You've seen a 2D map (or photo) of the Earth before, right? What GPS satellites do is provide this 2D equivalent of the Earth (which is spherical) to GPSrs so they can "view" the Earth in X and Y coordinates (i.e. Lat & Lon).

GPSr only "appears" to understand addresses because the map providers(Navteq & TeleAtlas) "map" coordinates to addresses so you can search by human-friendly addresses.

If you don't want to learn how to obtain coordinates for your desired addresses (which is easy, just search for it in this forum including the FAQ), you can use your GPSr to find each location and save them as your favorites. These saved locations are stored in Current.gpx with coordinates so you can create your own POIs from it.

On the other hand, like Phil said, if you just want a list of addresses for some other purposes, then consider using PDA or your mobile phone's address book.

Just download Google Earth for free. You can put the address in and it will take you there. Put the cursor over the location and read the lat/long at the bottom. Use a converter to convert the lat/long from hours, minutes, seconds to hours "dot" decimal format. I'm sure you can change the settings on GE, but I didn't see where to do it. I just used the following converter...

Be careful with Google Earth or any of the other map programs which "locate" addresses. In many cases the coordinates are not even close to the actual location of the address in question. In other cases, they are "close", but that isn't much help when trying to locate a building, etc in a neighborhood.

This is from errors in the mapping address information.

We have been doing quite a bit of GPS locating of addresses and have found numerous errors in the address lookup feature.

Majority of Windows applications follow the MS convention of
'Tools' -> 'Options' menu for customization.
