I paid £19.99 for the memory map iphone app.
Since the price drop someone stated on the reviews section of the App Store that you could use the extra money you paid to buy maps.
I have no knowledge of any such arrangement.
I looked at my account and it says 'You have unused resources which are available for activation.' followed by a list of maps.
How exactly do I access these unused resources?
If you go to the map folder > MORE MAPS > DIGITAL MAP SHOP, then click MAP TYPES > SHOW ALL, you should see these maps listed for download. Most are simply sample areas of larger maps.
