Mazda NB1 and Europe map size (bigger than SD Card)
I've seen on the website partial maps of Europe - terrible value indeed as they're barely any cheaper than the full Europe map. And I do not want to lose countries I've already paid for with my vehicle - if I purchase western Europe I'll lose access to the maps I have for the Balkans for instance.
Tom Tom home does not offer those maps anyway. It only offers full continents.
