Did you get the "Generation 5" 7.1 disc and not the gen. 2/3, or gen. 4? My wife purchased a brand new version 7.1 for me from the dealer for $295.00 and we found out later that it's the generation 5 for the newer IS....no refunds!!! Now she just ordered the gen. 2/3 for me.....the gen. 5 disc wouldn't even register in my 2/3 unit.
