I must add that "latest map" have to mean "current map", that is, this version you are upgrading to. Or did they relase one version in late July och August? Almost everyone will have to pay to get up-to-date.
Sorry for the confusion, I was in a hurry and I didn't understand it right. Now I have it up and running. I've paid 20,85 #8364; for the map of Spain, Portugal and Andorra (v725) and 20,85#8364; for the subscription for a year. That's a total of 48,65 #8364;.
I already have updated my TomTom One v3 with the latest map. Now I'll have to verify which correctios that I made are already present and which have to be applied once again (annoying, but there aren't that many.)
