Columbus/Parrot integration issues

Well after much swearing and trying to get my hands into ridiculously small spaces i have managed to fit my Columbus head unit and MDI kit.

Only issue was getting the extra loom to fit behind the headunit and locating the MDI kit. I ended up fitting the MDI kit to the right of the head unit and feeding the iphone cable into the top storage box which works a treat. I still have full iphone control as well from the phone or via the headunit which is great and i was not expecting.

Everything works perfectly except......

My parrot handsfree kit still works but i get no playback through the speakers anymore??? I am guessing there is probably some wiring that needs swapping over on the loom but not got a clue which.

Any ideas?
