Hey guys, I presently have 4 cards, 2 gold, 1 hotmaps premium and 1 platnium +, looking at updating my maps. Can I update any of them, including the platinum + ? And can I keep on updating them, or is it done once a year ? I have 2 units so I don't really need 4 cards. Is there a lot of updates done in Ontario or are they mostly done in the states ?

Thx
Luc
