Sorry, spell checker changed "no" to "to"
Basically I've removed pin 7, and moved pin 5 to pin 7 as suggested.
I no have no right audio channel from the iPod interface, but i do on the radio, so the problem is with the dock, not the stereo output.
Pin 7 is listed as AUX in (R), but the iPod interface doesn't use the AUX input does it?
