Question about the stock stereo

[Rotorflyr]

Im thinking about adding a satellite set up into my svx, and am considering using one of the PNP versions instead of installing a whole new deck which also gives me the option of a home docking station and would like to know what (if any) aux inputs are on the back (or side as the case may be) of the stock stereo to run an audio cable to??
The system will allow you to use an FM transmiter feature, but I figure the sound will be better using a cable

I do have the stock CD player and if there is only one input (which wouldn't surprise me) would it be possible to use a splitter and share the input jack?
