I've been trying to find out if I can get a firmware upgrade for my RNS-E in my 05 allroad. After visiting several forums and even calling Audi of America twice (getting different responses each time, one saying that there wasn't an upgrade and one saying that there was)I'm pretty confused as to whether I can get a firmware upgrade or not. I've read some forums where an upgrade will get rid of the annoying warning that comes up every time you start the car and add some newer features to my system, essentially upgrading it to an 09 model. Any help in this would be greatly appreciated. Thanks.
