Does anyone know how I can update North America navigation on MY 2010 A6? I did find an eBay supplier that offered many updates (at very reasonable price) but none for 2010. Also found youtube video (in a foreign language) that showed how to activate SW update functionality that leads to selecting either dvd or SD1 or SD2 card. Also spoke with Audi rep who told me 2010 update requires dealer installation. Not sure why this is the case but high dealer cost is not better than using my iPhone.

Any ideas?

Thanks
