Well I broke down a while back and bought the Autocom SuperPro AVI. The dealer got a discount on them with their initial order of the new models so it became a little easiler to justify.

I installed it a few days ago and tested it out yesterday. The intercom works good at any speed. The VOX function is adjustable and even at the most sensitive setting it never turned on without speaking first. The speakers are good however not the best for music sound quality but not too terribly bad. The auto volume control feature works nice.
I velcroed (sp?) the unit to the inside of my empty/modified air box. I put a connector in the power supply line so the unit can be removed. I used the heated grip plug under the gas tank for power by putting a couple of pins on the end of the power supply wires and plugging them into the heated grip plug. I then used heat shrink tubing to secure and protect the connection. It switches on and off with the ignition. Any components that I am going to plug in such as an MP3 player I can just plug it in and put it in the former air box.
