Before you send it in...I had already sent mine in before I remembered to include: needs more memory for blackberry interface. Needs to store at least 10,000 names, Needs real time NAV. Needs rear fog lamp option.
haha, none of those are important to me, so it'd be a bit of false feedback if I said that. Though I likely will say it needs a whole new entertainment system all together which will take care of your first 2 complaints.
There are surveys ( and I have received as many as everyone else) and then there's JD Powers. This is the only one that Audi asks you to complete and probably the only one they pay attention to. All the others are just using your time and making money off your opinion. A crisp buck doesn't sway me one way or another but it's a nice marketing gesture.
