...the short answer is yes... but the audio quality for the Music will be perhaps less than desired...
Yes, exactly what Al said. If you have a 2820, System 5 helmet, and the WCS-1 helmet audio system, you can get the voice directions, phone, and the music all delivered to the helmet.
The quality of the voice directions and the incoming phone audio is excellent. Outgoing phone audio (what you say to people you are talking with) sounds a tiny bit odd - a bit like you are talking through a tube - but, considering that you are basically talking with a fishbowl over your head, it's really quite amazing that the outgoing audio quality is as good as it actually is. Sort of like a dog walking on its hind legs - what's remarkable is that the dog can do it at all, not that the dog doesn't do a perfect job of it.
Outgoing phone audio is certainly good enough for conveying information, speaking with people you know, stuff like that, but I really don't think I would attempt a half-hour long conversation to try and conclude a critical business deal whilst riding down the road, if you know what I mean. The problem is not with the quality of the hardware, it is with the wind noise and the echo from the fishbowl over your head. If, by example, I plug the GPSR into the wall outlet in my hotel room, put the helmet on the desk, then make a phone call via the helmet (while directing my voice at the two microphones in the helmet sitting on the desk - not actually wearing the helmet), it sounds just as good as any other Bluetooth phone headset.
The music delivered by Bluetooth will be mono - though you will hear it from the speakers on both sides - and it will have quite a limited frequency response, ending at 3,000 Hz. It's better than nothing, but closer in quality to an AM radio in a classic car than to a Walkman with ear buds.
Contrary to earlier rumors and speculation, there are NO PROBLEMS with battery life on the WCS-1 system. I rode from Budapest to Zurich yesterday on one single charge, with the helmet turned on all the time, and the GPSR in use (broadcasting voice, traffic, and speed camera messages) all the way. That's more than enough endurance for me.
The bottom line for sound quality, though, is that it is a
functional system, not a
high fidelity system.
