Preloaded POI

I also looked for this. It seems that the POI data is part of the map which comes from NavTeq and there isn't a listing or databas of these. I found it to be worng about 15% of the time for my area, mostly with restaurants. A lot of what was listed has been out of business for two years or more. Gas stations were spot on and listed all the ones in my area. I didn't check retail stores. Custom POIs don't take a lot of space. 2MB will hold many thousands of them.

I do not know of a list of every poi. But they are very complete on most chain stores and many locals that have been there for a long time. I have made some custom poi's of rest areas and parks - information that is important for my uses - and use the factory ones for all the rest.

Just remember that if the store is new or moved in the past 2 years in may not be right. That is the benefit of your custom poi's...you know exactly what is in the file and you can make corrections. You will like the c330.

I noticed the other day that my c330 doesn't have those listed in it, or at least around Knoxville.

By doing a search by name I found 1 O'Charley's at W. Cumberland Ave, 1 on S Mall Rd, and 1 on Kingston Pike - all in Knoxville !that was in the built in POIs on my C340. Just went to "Near" Knoxville and then "Spelled Name "O'Charley"

My monster combined restaurant POI file, which will never make it on here for various reasons, contains over 40,000 entries and is only 5 megs.

Some things to keep in mind:

Search is separate. If you load one that is already there, a search in the custom POI's will find custom ones only and a general search will find only pre-loaded ones.

Also - I've found while the custom ones are more up-to-date, often the pre-loaded ones are more useful.

For example - if I search the pre-loaded database for Publix, I may come up with Publix - Enterprise Road, Publix - Main Street, Publix - 7th Avenue. It's pretty easy to find the one I want. If I use the custom POI, I might come up with Publix - 2.5 mi NW, Publix 3.5 mi SW, Publix 2.8 mi NE.

In general, if you know the general area and want to find a specific location, the pre-loaded POI's generally work better. If you are in an unfamiliar city and just want to find the closest location and be sure it is still there, the custom POI's are probably better.

(Similar to how the GPS in general does a better job if you don't know the area and don't know shortcuts that it doesn't consider.)

It has been mentioned here before, if you need more space, you can get it by getting rid of all the languages you dont't need. They take a lot of space on the drive.
You can find directions on how to do this by looking it up here.
