While I was searching the net today I found some good information sources about the navigation system updates. As you know navigation system works with the sd card that is installed at slot 2. All the map is installed in it and system uses these map from sd card. So if you can update the map in this sd card, you will always have the updated maps. Today vw's discover media, skoda's amundsen and seat's 5,8 inch navigation systems work at the same way. At the links below you can find discover media's and amundsen's map updates. They are most efficaciously same. And I think it is also same for Seat's system. 1)For VW: http://www.navigation.com/is-bin/IN...t=application/ApplicationFrame_campaign_light How to update: http://www.navigation.com/is-bin/IN...t=application/ApplicationFrame_campaign_light 2)For Skoda: http://www.navigation.com/is-bin/IN...dsen&&NewDomainName=Navteq-NavteqEurope-Site& How to update: http://www.navigation.com/is-bin/IN...ions&&NewDomainName=Navteq-NavteqEurope-Site& These files are approximately 4,5 GB. If friends who have navigation system in their Leons can try this and inform us, we will be very happy. Thanks. And you do not have to install anything to your car's system. Just download the map. Put it in to sd car and locate it to slot 2. If it doesn't work you can locate your original sd card. That is all. Note: These map updates are free for VW and Skoda now. For example if you want to update your Opel's maps, it costs 99 euro. Really expensive.
