I have a Dual HD radio in my truck. It has a front side USB and AUX inputs. Bluetooth for the phone ($50 extra) and pushes my big Kenwood box speakers behind the back seat real well. Troy State University is the only local HD station (classical/talk radio) but when I get away from here, particularly Atlanta, there are tons of HD stations. The clarity and depth are truly amazing for over the air broadcast. In my opinion it sounds better than a CD. I particularly wanted the USB input as I've loaded a ton of songs on my 8 Gb stick and listen to what I want to listen to when I'm driving. The model number is XHD6425 and Crutchfield has it for sale for $149 right now. Comes with an installation kit free when you buy it from Crutchfield. Went right in in about an hour. No special antenna is needed. I am very happy to say the least. I have been buying Kenwood and Sony products for a long time but they don't seem to last longer than a year. The remote is very handy also.
