Each Garmin GPS device comes preloaded with numerous points of interest, or POIs. However, any one of these POIs may not have sufficient information, such as rapid speed reductions, red light cameras or known areas of traffic congestion. Software like GPS Babel and GeePeeEx Editor lets you make changes and updates to the existing database file, entering the changes in pre-defined fields. You can even use Microsoft Excel or another spreadsheet program to make edits in comma-separated value format. Using Garmin’s POI Loader software lets you send the modified file, converting it to Garmin’s proprietary GPI format. Writer Bio
