I have the upgraded in my Charger HC and in my wife's Summit. The GC Summit blows the Chargers away! I got the upgraded in my TH as well. For a factory system, it's pretty imnpressive. Only system I've thought was better is the Lexus Mark Levinson system. Holy crap that sounds so sweet. I had a 2012 Mercedes S63 with the upgraded $7000 optioned Bang and Olfson and the Jeep system blew that away. It's a no brainer in my opinion.
