I agree the Custom Auto Sounds USA 6 stinks. I'm talking about the USA 66 AMFM. I had the USA 6 and couldn't stand it either. The sound was terrible and everytime I changed radio stations I heard a humming feedback noise. I saw the 66 AMFM and decided to try it and it is WAY BETTER than the USA6 is. The USA 6 looks cheap IMHO but the 66 AMFM is a first class reproduction of the ultra rare AM/FM radio that was an original option on the 66 Mustang. The radio preset buttons actually control the external plug ins, like CD changers and such, but the tuning buttons are manual just like original. I just set mine to the local classic rock station and I keep an external CD player handy when I want to listen to my CDs.
