Data Loggers for TomTom
The simplest data logger tool is the NMEA (National Marine Electronics Association) Logger tool. This will record all of the nmea data collected from your receiver, and it places this information into a log file, which you can save either to your Flash memory or a memory card. The program will create new logs any time you turn on the device.
Another similar log creation program is the TTTracklog. This also records nmea data, and it will also log GPX (GPS exchange format) track files. You do not need to do anything once you install this program. It will continue to record data as long as it is installed. It will work as a background program; you just need to download the files to your computer to view them.
If you want more detailed memory, however, you may want to go for the Tripmaster. This program logs your exact GPS position, and it can save this information to GPX or KML (keyhole markup language) files. You can set this program up to record your exact (Real) location or the corrected GPS information from TomTom. If you want to know exactly where you were, you should probably go with the Real location setting.
Another advanced GPS logger is the Event Logger. It creates GPX files, and it logs your location at 10 second intervals. This will provide you with most street map locations, but you could miss some smaller streets and/or data.
