CDR23 without MOST bus?
 

I was going to do the lazy, and just wire up a FM modulator but when I pulled out the stereo I got an interesting surprise. The optic cable is just looping back!

Has anyone else seen this? I'm now planning on just wiring up my Parrot kit using the standard iso wiring approach. Should I bother ordering the telephone mute cable? Maybe I should re-consider getting a new head unit now that I know there is no MOST bus to give me grief...

This is in an 03 S.
