Connecting to MP3 Player to Harmony with Sony CD Changer

[GagHalfrunt]

Hi

I have a weird combination of a Harmony head unit which has a Sony CD changer hanging off it. It uses an InCarTech box in the middle, and to be honest looks factory fitted which is odd.

I have a Sansa Clip music player containing FLACs. Is there any way I can get this hooked up on the Sony bus and retain my CD changer?

I've seen devices like these:

I'm not sure that I can use it though as I think Sony head units have both Mode and Source buttons and it uses those to select between sources.

Selecting The Auxiliary Device: On the Sony changer controller head unit, press "SOURCE" repeatedly until "CD" is selected. Press "MODE" repeatedly until the device you want to listen to is selected. The head unit will cycle through each unit in the following order: CD1 (CD/MD changer) > CD2/AUX1 > CD3/AUX2 > CD4/USB. When CD1 is selected, the CD/MD changer will automatically start playing. When any other source is selected, playback of that unit will have to be manually started and the volume adjusted. As the volume settings of each connected device may differ, the volume of each device should be set to a similar level as the CD/MD changer.

Any ways around this? I can't afford to spend more than £50 to source this out.
