Thanks for that link Mike. It appears that install was done on a non-BOSE equipped car, so I'm still curious to know if there are any issues with that.
The ICELink plugs into the CD changer socket on the back of the head unit, and it says clearly on the Denison site that you cannot have both the ICELink and a CD changer fitted for this reason. But I'm not sure if the BOSE system has a seperate CD changer or if it's one of those head units with the changer part integral to it (and if so, if it even has an external changer socket).
Loving the Zed!
