Where can I find the latest maps for the XA-NV400?
I have the TomTom XA-NV400 which plugs into my Sony XAV-AX100 head unit. The TomTom XA-NV400 has a removable SD card that I can use to upgrade the maps. I can't find where the latest maps for this unit are hosted (specifically the United States map).
The closest I could find was this help topic, linking to the latest Western Europe maps.
Where are the latest maps for this device hosted?
