So, nothing comes through the headset, either rider or passenger, but the speakers work. And you have an audio source you can hear through the speakers, and if you change to headsets (headset icon on the disply, not a speaker icon) And the volume is up, you're not mutes, your switchology is right?
I did some cruising on the other boards, and I found a couple of things that might help.
Somebody suggested removing fuse #22 and letting it sit for a while. This de-powers the radio unit, and lets it bleed down, so you get a reset. Sometimes they have a brain-fart.
Another problem like yours was resolved by finding that the driver's headset cord had been pinched by the aircleaner cover when someone did a filter change, and it shorted the headset part of the system, and no workie. You'd have to pull the shelter to check this, but it seems like a pretty good possibility on a 2001 bike that has certainly had the shelter off, and I'd hope the filter changed.
There are other places the wires can get pinched, you should check them all the way back. And, perhaps unplug one, see iif the problem goes away, then the other one. That would eliminate a shorted connector/wie on the bike side. Unless they were both shorted, which is very unlikely. Possible, but ....not likely.
This thread is interesting.. Looks like it might apply..

I've jumped my '03 , audio on, with no problem, but who knows?
A bike that is the age of yours can have corroded pins in the connectors, too.
Do you have a CB? (I'm guessing not) Is the squelch all the way up if you do?
This probably isn't it, but is your intercom mute turned down? (Left volume button, push once? twice? I forget.. turn it to zero.
The only other thing I could think of is the big plugs under the radio on the shelter. If those aren't plugged in tight, you can have problems.
If the headset wires are OK, and nothing else works, I'd think it's the audio unit itself.
