Up grades for TT one v3

[etaylor]

I am new to tomtom and now I have the v3 one ,can the TT one v3 be upgraded? How can they put the entire USA map on less than half a gb? Why did they leave off a slot for a memory card?

IIRC, the US/Canada map is around 800MB, what exactly is the map named when you check the version?

If you were to get a new map, you would have to replace the new one with the old.

You always update the firmwire, but upgrade memory you can not.

Don't know why TomTom made a unit without a SD slot. It does give this unit limitations.
