Summary: This is my second purchase of an excelon and I love it. Love all the setting so I can fine tune it, not preset EQ. Bought as a gift but did the install myself. I will definitely by Kenwood excelon again.
Summary: I purchased an x397 for my truck. I went with the Kenwood because I had such a good experience with an older Kenwood U248U. I went with the low end of the Excelon line because it was on sale at the same price as the non-Excelon, and because my installer said it was good, worked well with the iphone, was very durable. Good points: - Big honkin' volume knob: this knob is undercut around the edge so its easy to get a good grip on it.
Summary: I bought this plus installation from AudioExpress near where I live at. It does everything that it says, and yes, buttons 1 and 2 can be used to vote Thumbs Down or Thumbs Up if you connect your iPhone to your Pandora App. I noticed that the stereo will actually determine whether or not your Pandora app is turned on and will immediately switch to Pandora Mode. However, the controls are not very advanced or detailed.
