I just updated my 2013 model TomTom Rider to the February 2020 maps release (v1045) and was surprised to find that I was able to install the entire USA/Canada/Mexico map. A few months ago when I went to update the software told me that I didn't have capacity any more and that I'd have to choose only a section of the Americas to have on my device at any given point in time.
Everything seems to be working fine I was just wondering why it went back to being able to fit! I'm rather glad that it does as hooking up the device to the laptop to change maps is a bit of a pain. Thanks!
