View .POI file in Mapsource

.POI format?

Do you mean GPI format, perhaps?

You can't view GPI files in MapSource. MapSource will open GPX files. So, if you convert your source files to GPX, you can open them in MapSource.

I seem to recall a while ago some past discussion about someone creating a GPI viewer. You might search and see if you can find that discussion.

Or if you really mean .POI format, those files won't work on Garmin units.

Speaking of which, it seems like most of the time when I try to use POI Editor for a batch convert from .csv to .gpx, the conversion fails with a string of errors, mostly listing a bunch of .csv formatting problems. I like to view POI files in MapSource before I load them on the GPS, but at least half of the files won't convert, even though they load into the GPS just fine.

Any idea how I can fix this problem?

Have you tried Phil Hornby's Editor? There is a trial version that you could use to see if it automatically fixes the problem. http://geepeeex.googlepages.com/

I guess if they are all csv formatting issues, you might be able to use POI Verifier also: http://poiverifier.com/

I did mean .GPI format. I have tried GPS Babel which gets the locations and names but loses the proximity alert information. I can't seem to find any utility that would retain the proximity alerts on conversion from .GPI to either .GPX, or alternatively .GDB

Is there a reason you can't just convert the original data files or is this a compiled file that came from somewhere else?

I did some searching and found this. I haven't tried it, so I don't know if it will retain all the data. I'm guessing that you are trying to edit a speed camera database compiled by others. You may not be able to do what you want.
