I am trying to use my Navicore key for Wayfinder, just flashed my N800 today, deactivated the key prior to flashing per another thread I found. When I enter the key into Wayfinder it says "License Activated: Navigation North-America" so I click 'OK' and it asks me to put in the key again, it is just a loop, can never get past this...any ideas?

OK, you have to download map data or it will not let you activate the Wayfinder software, at least thats what it seems like in my case. As soon as I downloaded the data for my region it let me have full access to the features.

Second that, thanks for the post. I also found that I could toss all the 2007 Navicore stuff that was on the SD card. As long as mapdata_whatever is in the maps folder on the SD all is well.
