A-GPS aka Assisted GPS uses regular standards to connect to satellite (just like a regular GPD device) PLUS use the aid of cellular towers to pinpoint the location faster. So, it uses 2 methods to pinpoints your location as apposed to one.
Before, A-GPS was commonly used in smartphones, it was heavily used by ambulances for its better performance comparing to regular GPS.
This applies to other navigation apps, not only TomTom.
