Seen these on the American Muscle webpage...looks like a nice upgrade from my 2012 non-navi unit....

But I'm curious as to how they affect the Shaker system....I have the Sync so I fit the requirements but the webpage doesn't mention Shaker systems anywhere...and are they worth it? I want to make sure the system itself is worth the money spent...if it's full of bugs and doesn't sound as good as OE I won't do it.
