I have the LUX 2011 model with the 8.4Nav and Voice Recognition and Handsfree uconnect phone system. THe sound is clear from both sides. But I have issues with the USB and SD card readers. THey are very picky as to what types of files and how the files are written to the drives including kb/sec. Pretty ridiculous. I had a 2010 Ford Fusion SEL with the sync system that worked awesome, never had to repeat voice commands, could jump from artist to artist without a problem just by saying it to the car. Dodge needs to take some lessons from them to get this technology working right. I like all the bells and whistles in my car, but if they don't woek right then thats a waste of my money, and frustrating as $%&^.
