Came to this forum 2 weeks ago looking for a repair option for my HK radio. 06 Street Glide with no audio. Originally replaced it with a Sony Aftermarket. Never really liked the way it looked on the bike, and last month, it too crapped out. Based on the reviews here and on other forums, I contacted Iron Cross Audio. The guys there explained what happened in both situations (bad fairing brackets shaking the radio to death). Sent my HK to them for repair and an iPod cable. All I can say is wow. Great customer service begining to end. Fast turn around and the amount of work done to the radio beyond the no audio is impressive.
Thanks to everyone here for the recommendation, and thanks to Iron Cross Audio for all they did
