I have a Stiletto II. I have a cradle in the truck, at home attached to my home stereo, and one on my desk at work.
Before our trip over Labor Day, I wanted to figure out how to use it on the FJR via the Starcom.
I bought a vehicle kit and put the cradle into the cell phone pouch on the tank bag. The vehicle kit comes with a cigarette lighter power adapter, so I bought one of the DIN-to-cigarette lighter dongle thingies and use the lead for the battery tender to supply the power, rather than running another lead off the battery.
For the antenna, I just used velcro on top of the front brake reservoir and ran the cord to the under-the-seat area for the 750,000 feet of extra antenna length.
There's also a audio-out cord going from the cradle to the Starcom under the seat. The under-seat area is kinda messy (Starcom, cigarette lighter power adapter thingy, 750,000 feet of extra antenna wire coiled up) but I don't care.
So, I have 3 wires (audio out, antenna, and incoming power) running from under the front of the seat into the little Audio access hole in the front of the tank bag (Rapid Transit something-or-other magnetic), just enough extra of all 3 wires is inside the tank bag allowing me to swing the bag out of the way for fuel, and into the cell phone pouch to the cradle.
So far, so good. We ran 1200 miles over Labor Day weekend riding from Columbus to the Finger Lakes and back, and ran 1100 miles this past weekend at EOM, all while listening to live Sirius radio. Since the Stiletto is so small, when we would stop and go, say, inside a restaurant, I would just power it down, pull it out of the cradle, and put it in my pocket or Givi bag.
The only drawback to this setup is it is difficult to change the channel while moving. I think I could do it, but it would require me taking my eyes off the road longer than I'm comfortable doing.
