I've downloaded the map Topo France v2 (Mapsource) which I found here http://www.navitotal.com/forums/showthread.php?1351-Garmin-Topo-France-v2-(Mapsource)&highlight=topo. I installed the map... till there everything went fine.
Now, when I open Mapsource it says the map is locked. The three options to choose are: unlock online, copyright and message. The last two are unusefull. With the option unlock online, a serial number and productcode is needed.
Could someone please help me. We are leaving on a holiday next week and it would be nice if the map would work on my Dakota 20.
Many thanks in advance.
Sorry for my bad English.
