Igot a TomTom XL IQ Routes 340 for Christmas today, and for fun, I took it on a joyride. After the initial set-up, I had my map, and my TomTom worked just fine - it got me to and from where I needed to go.
I got home and decided I wanted some new voices, so I plugged it into my computer and installed TomTom Home. It told me it wanted to update my map ...
