Lacks many basic features

I think this is a great idea, but this system simply lacks many basic features that I expected it to have. The first is a scan button for the radio, it doesn't have one. I also expected to be able to load my own wallpaper. You can't. I expected the included wallpaper to have more variety. There are only about seven choices and six of them are nothing more that a few colored dots of light on the screen. I was hoping to find one to compliment factory dash lights instead of making the radio stick out like a sore thumb. No such luck. I expected some sort of visual animation while playing music. There isn't any. The features it does have seem to work great. Perhaps my expectations were just to high.
