Duplicate POI points

I am wondering what happens if there are duplicate poi points in my Garmin.
Which one will it use?

Duplicate POI

As far as I am aware, Garmin POI loader will overwrite the same POI's.
I have a Nuvi 260 and don't get duplicates when I update.

Duplicate POI

If the POIs are truly duplicates (all information including latitude, longitude, name etc is identical), the unit will overwrite them and only use one. If it's really close -- like say two custom poi's that you have downloaded in different files, both for the same poi but the latitude and longitude are off by 0.0001, they will both show up. The only way to eliminate this is before you import the POI file to your machine -- delete the dups in a CSV file format.

Good luck,

As mentioned above, if ALL the information is duplicated, POILoader will overwrite and only one POI will be stored. If, however, the positioning data is close, but not exactly the same, multiple POI's will be atored.

Bulk uploads

I'm just about to try a bulk upload. I'm just about to test this out and see if there are duplicates or if they delete.

Best practice

I think it is best practice to always use the POI Loader to remove the old POI file from the Garmin before uploading the new one.

Duplicate POI points

totally agree with bgtee i had downloaded several times certain poi's after restarting my unit i found that i had multiple instances of the same poi with identical features, so i reckon that you should use the poi loader to remove previous custom poi's then disconnect from the PC ,reconnect then reload a new set of poi's , always backup your poi file to your PC and before adding any new poi's put them into your poi folder on your PC

remembering to remove the file before you update it so that you don't get ant duplicates.

If all are the same, than it will just overwrite and use one...no worries.
