I don't think there is a right or wrong answer to this. We all have different needs/wants. I didn't get it because I don't like the dash and figured I would not use it. Without it, you still get voice activation, directions, weather, traffic, sports, etc... Downloading music to my car is not a priority either. And we had a huge laugh about the climate control considering the limited space we are talking about. The HD radio might be nice, but I like to listen to CDs when I am listening to any music. You can also use a media player, so downloading music to the cars hard drive is a mute point. I loaded my car, including glass roof, but I just didn't want the package. To some people though, it's a requirement and thats OK.
