BMW iPod connector
 

Hi everyone,
I've got a USASPEC PA12 that came factory installed with my X5 (3.0i). No DSP, stock business CD HU. Does anyone know where the main PA-12 unit could be located? All the photos online show it connected to the DSP in the trunk, but I don't have a DSP and I couldn't see anything remotely close to an audio connection in either side of the trunk panels.
