RE: twisted audio
I looked at those myself. Besides the look, which IMO does nothing for the bike, it doesn't work for me because it is a radio with MP3 capabilities. I remember when I had my Ultra that the bulk of my time was listening to my MP3 player hooked up to the HK unit cranking out my own tunes. I really never listened to the radio.
I am going with the Harley Boom windshield mount unit hooked up to my Iphone in the tank pouch. At $319.00 from LSHD I can download a lot of Itunes and listen to the songs I like and not have to listen to advertising. From what I have read the Boom windshield mount system gets good reviews as far as the sound, and IMO looks a lot nicer.
