Update your TomTom software.

I did it yesterday and what a difference in performance.

No joke - I did the upgrade on the One I have and - get this - it
provides instant lock on satellites.

I'm absolutely serious - instant lock. As in full lock - ten
satellites.

I have no idea how they did it, but it boots faster and you get a full
lock on position instantly.

It's also tracking much better and before, it wasn't bad at all.

They changed something and it's really for the better.

As in WAY better.
