Searched and read as much as I could find. OE US RNSE as far as I know. Currently: System SW index: 0150 HW index: H70 HU/Navi SW version V222027E Boot version V2200100D Audi SW version A2220134-280705 Burned the following files on a CDR, slowest speed, ISO9660 (also tried ISO9660 + Joliet), verified, closed CD: 00.VNS A2220141.MOT INDEX.TXT LDM.BIN LOADING.KWI Tried forcing upgrade with VCDS, 37, channel 97, 1. Nothing happens when I pop the CD in but it does seem to see that it is an upgrade CD as displayed on the screen when it's folded down. Original 2005 NAV DVD reads fine. Backup 2011 DVD has software files as well but won't upgrade either. The maps will eventually load after 10-15 minutes of "initialising" but I'm guessing it's taking this long because the software won't update. Any help would be appreciated.
