I bought a RNS-E (EU) Unit for my '00 A6 this week. All I have right now is the RNS-E unit, code card, GPS Antenna, Removal pins. Not exactly enough to get it up & running, but I got a low price on it so I knew I'd have to buy more. I have the cables on their way from EuroParts and they should be here tomarrow. I should be able to handle the install as the instructions look clear and easy to understand. But what I dont understand is the whole DVD Map Disk thing. Ok, lemme put it out there. The previous owner of the unit says it was pulled out of a 2004 A6. On the Audi website that sells the disks, they are selling several disks to get the entire US!! (For the 2004 A6). Everyones threads I have read sounds like their only using one disk. I travel alot from SE US to NE US, do i have to buy alot of disks to make the trip or what? I also dont understand the SW conversion stuff to morph it into a US version, but im banking that'll make more sense once I get the unit up and running. So whats up with the disks? Also will it work w/o the VAG setup cause my cluster is on its way out and I dont really wanna buy another one until next year. Any help on this is apprieciated.
