FYI - here's my dialog with Whistler:
Bryan: How may I help you today?
Bob: Has the Fuzion been discontinued
Bryan: Not discontinued. It's not currently being manufactured, but we do still support it with parts and service.
Bob: It looks like a better unit than the one that does not have the audio for my Harley
Bryan: Well, the display module isn't waterproof, so it's not really designed for use on a motorcycle.
Bob: Does the other one have an audio output?
Bryan: We do have the Cruisader model that is similar to the Fuzion, but is desinged for motorcycles.
Bob: Yes but can I get an audio output with the crusader
Bryan: The Cruisader does have an auxillary port that can be used for an audio device, but the only speaker that we make for the remote units isn't waterproof.
Bob: Does that mean I can connect the that port to the Aux input on my radio?
Bryan: Well, not exactly. It uses a digital signal, so it's just a normal headphone type connection.
Bryan: It wasn't really designed to be used with a sound system.
Bob: So I would need some sort of an adapter, if you don't sell one maybe I could get something form Radio Shack
Bryan: well, I don't know of any adapters, but you might send an email to one of our engineers and see if he knows of something that will work
