Ok a week ago I downloaded the red light camera file and installed it on my GPS. Well today I noticed there was another update so I downloaded and noticed the file was much smaller. How do I go about updating the old file to the new? Do I just put the new .csv in my Traffic folder with the old one and update?
If you have only one gpi file and it is named POI.gpi, the default name, doing what you suggest will result in a replacement file formed from all the csv files in the folder you point to as the source (assuming you are using POI loader).
The file is probably smaller because Miss POI has been removing locations that were either misreported as redlight cameras or where the cameras were never activated.
Put the new file in your Traffic folder and take the old one out. Then run POI Loader again to load ALL of your POIs to your GPS Unit.
