Anyone have experience with setting/switching the stock CD player into AUX mode (For CD changers)...?

I've installed the ipod adapter as listed above in the ebay link, connected the red power wire to the WHT/BLU 12volt+ from the wiring harness and the blk/gry to the ground...and when i plug in the IPOD it gets power (charges the battery)...so that's all good it seems.

the MBUS connector is plugged in as well, yet i am unable to switch the stock CD player to AUX mode...so either it doesn't recognize the cable/isn't getting a connection via mbus OR i'm just not setting the CD player to AUX mode correctly...i can only assume this is done by pressing the CD button. (which is labeled tpe./chg. above it) am i missing something?

i'm aware that an adapter of this nature doesn't provide CONTROL via the deck, but it *should* provide audio. especially considering that the MBUS-to-RCA adapter sold by the same company says it supports the very same alpine units, and i've read on other posts that people have done this setup using the RCA to stock alpine MBUS....isn't the transfer of data non-dependent on the headunit's capabilities? (as long as it has MBUS in the back)

/me pulls out his hair!

ANY HELP and i'll buy you a beer! THANKS.
