I've downloaded it and it work just fine on my RNS510.
I've just one question. Are this really 2012Q1 navteq maps?
I'm asking because in this VW RNS510 Western Europe V.9 (7920) there is an old street name on my work place and on the original VW RNS510 Western Europe V.6 that came with my 2010 car it has the correct street name.
Why cloud it be? A newer map having old street names in Portugal?
How can i see the map version and firmware version on my RNS510?
