If I remember correctly another forum indicates that TomTom is used for speed limits but not for navigation. HW 1 uses the on-board Navigon maps for that. HW 2 is starting to use other map providers. And hopefully soon HW-1 will also. The map on the touchscreen is from Google but the traffic information is from another provider. Supercharger info is from a Tesla in-house database. And Tesla software has to merge the data from all these sources. It is simpler just to email Tesla National Service,
[email protected], with your issue and let them contact the correct data provider.
