Correct, GPS satellites are broadcast only. The only way TomTom would know where you are is if you chose to use their traffic notifications system and TBH there would be that much data to store it would cost them an absolute fortune

Now mobile phones, thats different as the networks know exactly what cell you are connected to and also your phone is constantly searching for new ones that have better strength than the current one so they can triangulate your position if necessary
