The BLAU/8-pod connected to my CDR-220 radio worked well until i tried my new iPhone. Needless to day it did not work.
I did some searching and ended up purchasing this cable:

along with the 5V docking cable

My new iPhone now charges and plays on the stereo and mutes the stereo when a call comes in.
My wife also use it to play and her ipod photo.
Good luck!
