I too use a xma3 and this is specifically what it was designed to do. It has the added "auto-ducking" feature that mutes the stereo input when you have a GPS or Radar audio warning present. I use an inline volume control that was about $5 from Radio Shack IIRC. I actually prefer that to having a volume control on the unit as I have the unit in the tank bag and hang the R-S control outside. Which means not only can I adjust volume on the go, I can plug/unplug my in-ears without opening the tankbag.
