Thanks,
No water on bike is some time. I did try to hook up an ipod w aux wire and then is when this started. I had it do it last fall but then it started working again after I used elect spray. The radio switched back to radio when i took the aux wire out so it shouldn't be looking for vol fr the ipod? I guess I'll pull the fairing and disconnect and clean everything.
Edit: Can the average person change the diode and is the a way to check this, where is it located in the radio??

The only way to check that is on a bench. Unit has to be opened with the cd drive out and the circuit operating. Once the correct diode is isolated, most techs I've seen do it (myself included) need a microscope to change it.

Harmon Kardon Radio Issues
My 07 Ultra with the HK head unit has the identical failure that many folks seem to be experiencing. Sound cuts out while driving down the road. Display and control switches work fine....just no sound. The only way to get sound back is to either power cycle or flip the speaker switch on the dash and the sound will be back for anywhere from 10 seconds to 10 minutes before sound cuts out again. I'm 2 months out of warrenty. Any chance the dealer will help out? Sounds like a lot of folks have seen this problem.

Going to be a hit and miss with the dealer. Still worth a shot. If your dealer cant help, check out these guys (www.ironcrossaudio.com). They worked on my 06 radio for a no display issue and as part of the service installed some sort of modification to prevent that common audio cut out problem.

I am not sure I was very convincing when trying to explain this to the service manager. However, the day of my appointment it crapped out on the way. Your best bet is to get it to a shop (When it is malfunctioning) so they can see it. Once the SM saw what mine was doing. He said we'll have your new radio in a couple of days.

What have you found?? I have reverse problem in that vol won't go up, just down and now is stuck on mute. It wouldn't be a short else it wouldn't work at all. It does the same thing in the bass, tremble mode. Any help would be appreciated. So far I've loosen the switch housing and handle bar clamp and wiggled the wires, disconnected the battery for an hour and sprayed electric cleanner in the switch.

I have an 09 street glide was on a trip and all of a sudden i lose the volume and i turn the radio up and down and nothing worked. I was in alabama so i thought at the time it might be the heat. So i turn the radio off waited a little bit and turned it back on and it worked for a little while. Anyway this went on for my whole trip. As i got closer to getting home it was cool that day so i ruled out heat. I have hawg-wired amp and spearkers so i thought that was the problem. I called justin at hawg-wired and he said that harmon kardon radios have been having problems. I had an 06 sg and didnt have any problems and had the same amp and speakers hooked up. Justin told me to call tony at ironcross in new jersey and i talked to him today and he said it could be the circuit board and to check to see if the mounting bracket is broke. So i will have to see if dealer will take care of this.

Having the same problem losing sound and I have to cycle the power to get the sound to return. This works sometimes, was at dealer yesterday and mentioned this to the SM and he told me I had make an appointment during the week and then he would have to check the wiring and the impedence on my JM audio speakers. Sounds already like they are trying not to cover it under waranty.
