You can PM Lokiwolf and he'll send the firmware and VIM update and map links.
I am just going to use the firmware and VIM fixes and not the maps because I'm too damn stupid to figure out how to break up the 7 gigs of map info into two DVDs to transfer it to my unit.
Okay, my stupidity got me searching and I ended up on the Continental Site. http://www.rns510.de/technology.html
They are a little silly in their touting of the speed of their RNS 510 for VW, but I was struck that they say you can update data via the SD card.
So, I've got to ask: Can I transfer the new LokiWolf map data via SD card to the unit?
