I'm going to be leasing a new X5 4.4i this month and..to be honest..the only thing I dont like about the vehicle is the navigation system. I have played with the Nav on a friends X5 who has a 2004 model. Will there be any changes to the nwe X5's Nav that I will get over the 2004 model's? If so, what are they? Thanks for ur help. This forum rocks by the way.
