I've got this listed on E-bay for a "fair" price, but I willing to consider any fair offer from people here. This worked really well with my Sony setup and my Srius Starmate Replay. Check my positive feedback thru e-bay, you can check my references there - same name as here

A brief description:
This SON-AUX adapter allows you to use the changer input on your Sony receiver to add a Sony Brand CD changer AND provides an additional auxiliary RCA input for use with your Satellite Radio Receiver or any other line level source device, like a DVD player, I-Pod, VCR/VCP Playstation, MP3 player, and many others. This adapter will not work without a changer connected. The SON-AUX is designed to add an additional set of RCA inputs to your stereo system. Simply plug the SON-AUX into the single RCA inputs and it will give you an additional set of RCA inputs into your stereo
The SON-AUX is a current sensing device that will automatically interrupt the CD changer audio lines going to the Sony radio (and switch in an external RCA signal) whenever audio signal is detected on its RCA inputs. The CD Changer audio lines will reconnect to their previous state 10 seconds after no audio signal is detected by the SON-AUX on its RCA inputs. You can use the PIE part number 3.5-RCA6MM to convert the RCA plug to 3.5 mm. No wire cutting is required. This adapter can be used in addition to another adapter that gives you a single RCA input to convert the single input into dual inputs.
