This is where I mounted my Sirius:
That was just a quick install using a VSM I bought off of ebay. I later took it back apart and cleaned athe wires up, it is still in the same location though. I know its a Sportster but my Stratus will fit on that same dock. To wire the power, I actually bought an aux, cig lighter and wired it in a switched fuse so that the Sirius comes on the same as the radio, and just plugged the unit into it. The cig lighter plug on the unit actually reduces the voltage from 12 to 6. A lot of people fry their units by cutting it off.
