I am thinking of getting a Dension GW500 for my 2004 A8L. I think I remember reading that to use the iPod integration feature, the iPhone must be in airplane mode. Is this true? I would hate to have to get an additional iPod for my music. I finally got my BTUM puck working with my Audi. But of course I always want something new. How does the Bluetooth module work with the iPhone? Is it satisfactory? I saw a place in New Jersey that does installs. Is there anywhere in the Baltimore(MD)/Washington(DC) area that does installs.
